Question

the hotog eating champion eats 27.5 hot dogs in 4 minutes. at that rate how many does he eat in the 10 min competition?

Answer 1

68.75 hotdogs

Explanation:

lets say x = number of hotdogs

27.5/4 = x/10

use cross multiplication:

27.5 (10) = 4(x)

multiply

275 = 4x

divide both sides by 4 to isolate x

x = 68.75

Answer 2

68.8 hot dogs

Explanation:

27.5 ÷ 4 = 6.875 per minute

6.875x10 = 68.75 hot dogs
