Question 724198: Tshirts cost $10 shorts cost $15. If you have $90 to buy a total of 8 shirts and shorts how many of each can u buy? Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! 90=10X+15(8-X)
90=10X+120-15X
15X-10X=120-90
5X=30
X=30/5
X=6 T-SHIRTS CAN BE BOUGHT.
8-6=2 SHORTS CAN BE BOUGHT.
PROOF:
90=10*6+15*2
90=60+30
90=90
