You are ordering T-shirts for a family reunion. Tanya's T's charges a $40 set up fee and $7.50 per shirt. Sal's Shirts charges no set up fee and $10 per shirt. Which 2 equations represent the system that can be used to determine the number of shirts where the cost is the same for each company? *

y = 7,5x + 40

y = 10x

 

10x = 7,5x + 40  | - 7,5x

2,5x = 40           | : 2,5

     x = 16

     y =10*16

     y = 160
