For the first one, you do need to divide. The division should be: 286/26, to find how many invitations can be printed each minute.
286/26=11
The answer is C. 11 invitations can be printed each minute.
For the second problem, Amy runs 1 mile every 7.5 minutes. To find how many miles she runs in an hour, divide 7.5 by 60:
60/7.5=8
The answer is G. Amy runs 8 miles in an hour.
I hope this helps :)

You have two choices.
The minimum possible cost to operate your bat factory for a day is $390,
and there are two quantities of bats that both cost that much.
One possibility:
Produce no bats at all per day. Zero. Nada. None.
Cost = 0.06(0)² - 7.2(0) + 390 = $390 per day.
The other choice:
Produce 120 bats per day.
Cost = 0.06(120²) - 7.2(120) + 390
= 0.06(14,400) - 7.2(120) + 390
= 864 - 864 + 390
= $390 per day.
If you produce any other number of bats in a day ... more than zero
but not 120 ... then it will cost you more than $390 to operate the factory
that day.
