Answer: Yes, there are enough popcorn for eight 9- ounce bags.

Step-by-step explanation:

Since we have given that

From Machine A,

Amount of popcorn in 3 minutes = 12.75

Amount of popcorn in 1 minute is given by

$\frac{12.75}{3}=4.25\text{ ounces}$

Amount of popcorn in 10 minutes is given by

$4.25\times 10=42.5\text{ ounces }$

From Machine B,

Amount of popcorn in 4 minutes = 18 ounces

Amount of popcorn in 1 minute is given by

$\frac{18}{4}=4.5\text{ ounces}$

Amount of popcorn in 10 minutes is given by

$4.5\times 10=45\text{ ounces }$

Total amount of popcorn is given by

$42.5+45=87.5\text{ ounces}$

Now, there are eight 9-ounce bags means 72 ounces

Since 87.5 ounces is greater than 72 ounces .

So, there are enough for eight 9-ounce bags.
