Question

Louis is very hungry when he spots a hot dog stand. The stand sells soft drinks for $1.25 each and hot dogs for $2.50 each. Louis has $21 in his pocket and he really wants to buy one soft drink and as many hot dogs as he can purchase. How many hot dogs can he buy?

Answer 1

Answer:

7 hot dogs

Step-by-step explanation:

Set up an equation:

2.5x + 1.25 = 21

2.5x = 19.75

x = 7.9

You cannot buy .9 of a hot dog, so the answer is 7
