Question

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes. If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags? Explain.

Answer 1

Yes, they're will be enough

For A, it makes popcorn at 4.25 ounces per minute (12.75/3 = 4.25)

For B it makes popcorn at 4.5 ounces per minute (18/4 = 4.5)

Together they make 4.25 + 4.5 = 8.75 ounces per minute

For 10 minutes they make 8.75(10) = 87.5 ounces

to make 8 9 ounce bags means making 8(9) = 72 ounces

87.5> 72. There's more than enough in 10 minutes
