A shopper purchased 8 T-Shirts and 5 pairs of pants for $220. The next day, he purchased 5 T-Shirts and 1 pair of pants for $112. How much does each T-shirt and each pair of pants cost?

Answer 1

T-shirts cost $20; each pair of pants cost $12.

Explanation:

x is T-shirts ; y is each pair of pants

(8x+5y=220) -1

(5x+y=112) 5

----------------------

-8-5y=220

25+5y=560

----------------

17x=340

x=20
