B + b + b + b + b + 2b = 7b (add all the variables up )
7 x 10 = 70 ( since b = 10 substitute)
<u>Answer:</u>
C. Each additional t-shirt being printed will increase the total cost by $11.
<u>Step-by-step explanation:</u>
We know that the total cost of custom t-shirts, y, in dollars, for x t-shirts is given by:

Here 11 is the price of the shirt, x is the number of shirts that are printed and 25 might be some additional charges.
For each additional shirt that is printed, the total price, y, will increase by $11 so the correct answer option is C.
3/5 because it can't be 1/6 or 1/2 because they are 50% or smaller. Also it is 2/5 because if you count 20, 40, 60... up to 100 the third number is 50.
I think it takes him about 9 minutes and 25 seconds to run a mile
Let, that number = x
It would be: x * 25% = 21
x * 0.25 = 21
x = 21 / 0.25
x = 84
In short, Your Answer would be 84
Hope this helps!
