Question

Two customers walk up to a hot-dog stand, both have exactly $20 in their wallets. The first customer leaves the stand with 4 hot dogs and $8, the second customer leaves with 2 hot dogs and $14 leftover. Write an equation to find the cost of a single hotdog.

How much is a hotdog?

Answer 1

4H = 20-8 = 12

H = 12/4 = $3 for a hot dog

2H =20-14 = 6

H=6/2 = $3 the same price to the 2nd customer

Answer 2

4H = 20-8 = 12

H = 12/4 = $3 for a hot dog

2H =20-14 = 6

H=6/2 = $3 the same price to the 2nd customer
