Nicholas is buying shirts for his baseball team. He will pay $12.50 for each shirt plus a one-time fee of $37.00 for the design.
Which equation can be used to find y , the total cost to buy x shirts?

y = 12.5 x - 37.00

y = 37.00 x + 12.5

y = 12.5 x + 37.00

y = 37.00x - 12.5

It would be C.

Step-by-step explanation:

Y would be the Amount he would pay plus the one time fee. So there for it would be Y=12.5+37.00

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
