Sam screen prints custom t-shirts. He spends $320 each month for the paints he needs to make the shirts. He has found he can purchase quality plain shirts for $9.00 each. He screen prints the shirts and sells them at a local thrift shop for $24.00 each. The thrift shop charges him $100 per month to rent. How many shirts does Sam have to sell each month in order to break even?
Answers
Given parameters:
Cost of paint per month = $320
Cost of quality plain shirts = $9 each
Selling price = $24
Rent per month = $100
Unknown:
Number of shirts Sam has to sell to break even = ?
Solution :
Let the number of shirt sold each month = y
To break even the cost price per shirt must be equal to the selling price;
i.e;
Cost price = selling price at break even point;
Cost price = Cost of paint + Cost of quality plain shirt + Cost of rent
= 320 + 9y + 100
= 420 + 9y
Selling price = 24y
To break even;
420 + 9y = 24y
420 = j24y - 9y
420 = 15y
y = [tex]\frac{420}{15}[/tex] = 28
To break even, Sam must sell 28 shirts in a month.

A team of players are planning to prepare a t-shirt for their next season of games. The team has 13 members and each member will have 2 t-shirts. (a)If a t-shirt costs Rs. 375, what will be the total cost of the t-shirts for the team?(b)A sponsor agrees to pay Rs. 7020 out of the total cost of the t-shirts. The balance amount will be paid by each player. How much will be paid by each player?
Answers
Answer:
Rs. 210Step-by-step explanation:
Given that a t-shirt cost Rs. 375,
then 2 t-shirt will cost Rs. 375*2
=Rs.750
a. the total cost will be
13*750
=Rs.9750
b. a sponsor pays Rs.7020
there will be a deficit of
9750-7020
=2730
since there are 13 players each player will pay
2730/13
Rs. 210
The difference of 8 times a number and 2

Eight times the difference of a number and 2 is the same as 3 times the sum of the number and 3:
8(x - 2) = 3(x + 3)
Now just solve for x.

{y=2 2x+y=8
Answers
Explanation:
Substitute y with 2, so it would look like this:
2x+(2)=8
Then, subtract 2 (as it is by itself) from 8, which is on the other side, and it’ll look like this:
2x=6
Divide by 2 from both sides to isolate the variable, and you should get your answer:

A culture of bacteria has an initial population of 41000 bacteria and doubles every 5 hours. Using the formula P t = P 0 ⋅ 2 t d P t =P 0 ⋅2 d t , where P t P t is the population after t hours, P 0 P 0 is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 14 hours, to the nearest whole number?
Answers
Answer:
Population of bacteria in culture after 14 hours is 285541.
Step-by-step explanation:
We are given with [tex]P_{t} =P_{0}(2)^{\frac{d}{t}}[/tex]
Here initial population is 41000 , t=5 and d=14
Plug in these values into the formula
[tex]P_{14} =41000(2)^{\frac{14}{5} }[/tex]
Simplify
[tex]P_{14}= 41000(2)^{2.8}[/tex]
=41000(6.9644)
=285540.5847...
To the nearest whole number is 285541.
Answer:
285541.
Step-by-step explanation:
P0=41000-The initial population
t=14-Time elapsed
d=5-The doubling time
Pt=P0⋅2^t/d
Pt=41000⋅2^14/5-Plug in
Pt=285540.5848≈285541-(Use parenthesis in the calculator for the exponent)

So we know that Jordan bought 12 balls and Annika bought 16. We also know that they came is packages that each contain some number of balls. We are trying to find the greatest possible number of tennis balls in each package.
The greatest possible number of tennis balls in each package would be the greatest common factor of 12 and 16.
To find the greatest common factor of 12 and 16, lets first find all of the factors of 12 and the factors of 16.
12: 1, 2, 3, 4, 6, 12
16: 1, 2, 4, 8, 16
From looking at the factors of 12 and 16, we can find that the greatest common factor of 12 and 16 is 4. Therefore, the greatest possible number of tennis balls in each package would be 4.

Point Ris on line segment QS. Given QR = 3x – 8, QS = 3x, and
RS = 2x, determine the numerical length of RS.
Answer: RS
Submit Answer
attempt 1 out of 2
Answers
Answer:
RS = 8
Step-by-step explanation:
Given that R is on QS , then
QR + RS = QS , substitute values
3x - 8 + 2x = 3x , that is
5x - 8 = 3x ( subtract 3x from both sides )
2x - 8 = 0 ( add 8 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Thus
RS = 2x = 2 × 4 = 8
