Question

it costs LE Stor $10 to buy a shirt. the store sells the shirt for 2 1/2 times its cost. what is the profit for 100 of these shirts? hint: profit equals sakes minus cost.

Answer 1

10 times 100 = 1,000
10 times 2.5 = 2,500
2,500 minus 1,000 = 1,500 = profit

Answer 2

2 and 1/2 times it's cost

cost=10
profit=25-10=15

15 times 100=1500

profit is $1500
