Question

Mac hine A pops 12,75 ounces of popcorn in 3 minutes. Machine B pops 18 ounces of popcorn in 4minutes. If each machine pops popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags?

Answer 1

Answer:

NOT ENOUGH with which to fill eight 9-oz bags (72 oz).

Step-by-step explanation:

Rate at which Machine A operates:

12.75 oz

------------- = 4.25 oz/min

 3 min

Rate at which Machine B operates:

18 oz

---------- = 1.8 oz/min

10 min

In 10 min, Machine A will have popped (4.25)(10), or 42.5 oz popcorn, and

Machine B (1.8)(10), or 18 oz popcorn.  Together, the two machines will have popped (42.5 + 18) oz popcorn, or 60.5 oz.

This is NOT ENOUGH with which to fill eight 9-oz bags (72 oz).
