Answer:
#9) They made 12 sandwiches.
#10) They used 36 ounces of cheese and 48 ounces of meat in an hour.
Step-by-step explanation:
Let's begin with number 9.
For each sandwich, you would use 3+4 ounces of meat+cheese. That would mean, each sandwich would use 7 ounces. And if in total, they used 84 ounces of meat+cheese you would do...
84/7 = 12
So that would mean they made 12 sandwiches.
And then for number 10, you would just multiply 12 by each of the amounts used in each sandwich.
Cheese: 3*12 = 36 ounces
Meat: 4*12 = 48 ounces
So your two answers would be...
#9) They made 12 sandwiches.
#10) They used 36 ounces of cheese and 48 ounces of meat in an hour.
