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).
