The question is incomplete:
Lin is shopping for a couch with her dad and hears him ask the salesperson, "How much is your commission?" The salesperson says that her commission is 5.5% of the selling price. How much commission will the salesperson earn by selling a couch for $495?
Answer:
The salesperson will earn $27.22 as comission by selling a couch for $495.
Step-by-step explanation:
From the information given, you know that Lin's comission is 5.5% of the selling price, so in order to find the amount of the commision the salesperson will earn you have to calculate 5.5% of the selling price:
495*5.5%=27.22
According to this, the answer is that the salesperson will earn $27.22 as comission by selling a couch for $495.

Vertical Shift of Functions
Given a linear function
y = mx + b
The value of b is called the y-intercept or the y-coordinate where the line crosses the y-axis. If the function is shifted up by a value of k, then the new function is:
y' = mx + b + k
Similarily to shift the function down, the value of k is subtracted:
y''= mx + b - k
We are given the function:
[tex]\displaystyle y=\frac{2}{3}x+2[/tex]
1) To shift up the line, we select a value of k=10. The new shifted-up function is:
[tex]\displaystyle y=\frac{2}{3}x+2+10[/tex]
[tex]\displaystyle y=\frac{2}{3}x+12[/tex]
2) To shift down the line, we select a value of k=5. The new shifted-down function is:
[tex]\displaystyle y=\frac{2}{3}x+2-5[/tex]
[tex]\displaystyle y=\frac{2}{3}x-3[/tex]
3) To shift to the origin, we must select a specific value of k that cancels the y-intercept. We must shift down by k=2:
[tex]\displaystyle y=\frac{2}{3}x+2-2[/tex]
[tex]\displaystyle y=\frac{2}{3}x[/tex]
This new function has the y-intercept equal to 0
In a survey, patients are asked how long they sat in their doctor's waiting area. The results for two doctors are shown below.
Doctor #1 (waiting time in minutes): 5, 10, 10, 15, 20, 20, 20, 100
Doctor #2 (waiting time in minutes): 10, 10, 10, 20, 20, 20, 25, 25
Based on the results, what is the best measure of center to compare the data, and how do the measures compare?
The median is the best measure. The median waiting time for Doctor #1 is 7.5 minutes longer than for Doctor #2.
The mean is the best measure. The mean waiting time for Doctor #2 is 2.5 minutes longer than for Doctor #1.
The mean is the best measure. The mean waiting time for Doctor #1 is 7.5 minutes longer than for Doctor #2.

Answers
Answer:
See answers below with explanations
Step-by-step explanation:
Problem 1:
One number is 10 less than twice another.
This translates to n=2m-10
Their difference is 31
This translates to n-m=31
n-m=31
(2m-10)-m=31
m-10=31
m=41
n-41=31
n=72
Therefore the larger number is (B) 72
Problem 2:
Use elimination:
2x + y = 7
- 2x -3y = -1
4y = 8
y = 2
2x+2=7
2x=5
x=2.5
Therefore the solution is (A) {(2.5,2)}
Problem 3:
Use elimination:
x - y = 1
- x + y = -1
-2y = 2
Check if each answer eliminates to -2y=2:
2x - 3y = 6
4x + y = 4
-2x - 4y = 2 NO
4x - 3y = 6
4x - y = -4
-2y = 10 NO
4x + 3y = -6
4x - y = 4
4y = -10 NO
Neither answer is correct
Problem 4:
No visible items to match
Problem 5:
2(2x - y = -2)
4x - 2y = -4
x + 5y = 3
4x - 2y = -4

Answers
Answer:
The total amount of ticket sales on this day is $1530.
Step-by-step explanation:
From the information given, the total amount of ticket sales would be equal to the result of multiplying the number of regular tickets sold for its price plus the number of matinee tickets sold for its price, which would be:
Ticket sales=15R+12M, where
R= number of regular tickets sold= 70
M= number of matinee tickets sold= 40
Now, you can replace these values on the formula to find the total amount of ticket sales on this day:
Ticket sales=15(70)+12(40)
Ticket sales=1050+480
Ticket sales=1530
According to this, the answer is that the total amount of ticket sales on this day is $1530.

Write an equation to represent the relationship between the number of roses, x and the total costs of the roses, y. How much will 18 roses cost?
Answers
Answer:
Answer: The equation is
The cost of 18 roses is 53.10.
Step-by-step explanation:
Given:
A florist sells a dozen roses for 35.40. She sells individual roses for the same unit price.
Now, to find the cost of 18 roses and write an equation to represent the relationship between the number of roses, x, and the total cost of the roses, y.
1 dozen = 12.
Now, to get the cost of 18 roses we use unitary method:
If 12 roses cost = 35.40.
So, 1 roses cost = 2.95.
Thus, 18 roses cost = 53.10.
Therefore, the cost of 18 roses = 53.10.
Now, to write an equation the relationship between the number of roses and the total cost of the roses:
Cost of per rose = 2.95.
As, given in question:
Number of roses =
Total cost of the roses =
Total cost of the roses = Cost of per rose × Number of roses.
So, the equation is:
Therefore, the equation is And the cost of 18 roses is 53.10.
