Ana is going to a craft fair where she'll sell her handmade scarfs. She has six scarf designs, and she's made 15 of each. She's paid $128 for the booth, and each scarf costs $9.80 to make. How much should she charge for each scarf if she wants to break even after selling a third of her scarves?
Answer:
$33.6667
Step-by-step explanation:
Given the following :
Number of Scarf designs = 6
Number of each made = 15
Total scarfs = (15 * 6) = 90
Cost:
Booth = $128
Production cost per scarf = $9.80
Total production cost = $9.80 * 90 = $882
Total cost = $128 + $882 = $1010
Break even = profit - loss = 0
One third of scarves = 1/3 * 90 = 30
This means he must cover for the total cost of $1010 after selling 30 scarves
Hence price per scarf will be :
$1010 / 30
= $33.6667

(b^5)^3 x b^4 simplify
Answer:
b^19
Step-by-step explanation:
In the first factor, we need to use a formula to simplify. The formula is x^a^b = x^(ab). So that means that our first factor simplifies to b^15. Then we add up the powers to simplify it even more. b^15 * b^4 = b^19 using another formula. Therefore b^19 is the answer.

Suppose your business has a special checking account used just for paying the phone bill. The balance is $1530.00 this month. Next month the balance will be $1496.30, after that it will be $1432.60, and on the third month the balance will be $1428.90. Write an explicit formula to represent the balance in the account as an arithmetic sequence. How many months can you pay your phone bill without depositing any more money in the account?
A) An= 1530 + (n-1) ( -33.70); 46 months
B) An = 1530 + (n-1) (-33.70); 45 months
Please explain for me how you got the answer. Thank you so much
Answer:
B
Step-by-step explanation:
this month=1530
first month=1530-33.70=1496.30
Second =1496.30-63.70=1432.60
Third=1432.60-3.70=1428.90

4. A person is earning P600 per day to do a certain job. Express the total salary
S as a function of the number n of days that the person works.
Answer: S = P600 × n
Step-by-step explanation:
Amount earned per day = P600
Number of days used = n
The total salary s, will be the value of p600 multiplied by n. This will be:
= P600 × n
Therefore, the function regarding the total salary, s will be: P600 × n
What is the rate of change?
What is the Y- intercept?
Answer:
The y-intercept is -5 and I’m not sure about the rate of change
Step-by-step explanation:
The water level of a lake fell by 1 1/2 inches during a 1 2/3-week-long dry spell. Find the average rate at which the water level changed every week.
Answer: The average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.
Step-by-step explanation:
Given: Change in water level in [tex]1 \dfrac23[/tex] week = [tex]-1\dfrac12[/tex] inches = [tex]-\dfrac32[/tex] icnhes
To find : The average rate at which the water level changed every week.
i.e. Change in water level per week.
As [tex]1\dfrac23 = \dfrac52[/tex]
Change in water level in 1 week = [tex]-\dfrac{3}{2}\div\dfrac52 = -\dfrac32\times \dfrac25= -\dfrac35[/tex]
Hence, the average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.
We want to find the average rate of change at which the water level changed in a given time period.
We will find that the average rate of change is:
[tex]r = - 0.9 in/week[/tex]
We define the average rate of change as the quotient between the total change and the time it takes.
Here we have:
total change = -(1 + 1/2) in
Time = (1 + 2/3) weeks
Then the average rate of change is:
[tex]r = \frac{-(1 + 1/2) in}{(1 + 2/3) weeks} = - 0.9 in/week[/tex]
This means that the water level decreases, in average, 0.9 inches per week.

Which statement correctly compares the function shown on this graph with
the function y= 4x+2?
1 2 3 4 5
O A The function shown on the graph has a greater rate of change and
a higher starting point
O B. The function shown on the graph has a smaller rate of change, but
a higher starting point
O C. The function shown on the graph has a smaller rate of change and
a lower starting point
O D. The function shown on the graph has a greater rate of change but
a lower starting point
PLEASE ANSWER
Answer:
B. The function shown on the graph has a smaller rate of change, but a higher starting point.
Step-by-step explanation:
Rate of change = slope of a linear graph.
Given the linear function, [tex] y = 4x + 2 [/tex] , the rate of change here is represented by the slope of the line, which is 4.
Let's find the rate change of the function represented on the graph using slope formula:
Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Use coordinates of any two points on the line. Let's take,
[tex] (0, 4) = (x_1, y_1) [/tex]
[tex] (1, 7) = (x_2, y_2) [/tex]
Rate of change = [tex] \frac{7 - 4}{1 - 0} = \frac{3}{1} = 3 [/tex]
Rate of change of the linear function of the graph = 3.
Thus the function on the graph has a smaller rate of change, than the function, y = 4x + 2.
The starting value of a function is the y-intercept, that is, the value of y, when x = 0. It is the point at which the line intercepts the y-axis.
The starting value of the linear function, y = 4x + 2 is 2.
The starting value of the function on the graph is 4. At this point, x = 0.
Thus, the function on the graph has a higher starting point.
The statement that correctly compares the function shown on this graph with the function y= 4x+2 is:
B. The function shown on the graph has a smaller rate of change, but a higher starting point.

Answer:
-60
Step-by-step explanation:
Increase in population is given by positive sign
Change in population in 5 years = -300
Decrease in population is represented by negative sign
Change in population in 1 year = -300\5
= -60
Town's population faces a decrease of 60 residents each year.

A boat travels upstream on the Mississippi river for 3.5 hours. The return trip only takes 2.5 hours because the boat travels 2 miles per hour faster downstream due to the current. How far does the boat travel upstream? Which is the best equation to use?
Answer:
17.5 miles per hour
Step-by-step explanation:
A boat travels upstream on a Mississippi river for 3.5 hours
The return trip takes 2.5 hours
The boat travels 2 miles per hour faster downstream
Let y represent the speed that was travelled upsteam
3.5y = 2.5(y + 2)
3.5y = 2.5y + 5
3.5y - 2.5y = 5
y = 5
Therefore the distance travelled by the boat upstream can be calculated as follows
= 3.5 × 5
= 17.5 miles per hour
