Renting a sound system costs $24 for the first hour or any part of an hour then 12 for each additional hour or part of an hour the rental company does not prorate the charge or give refunds for unused time over what interval would u pay $60

4 hours

Step-by-step explanation:

24+12+12+12

above is the hint

4 hours

Step-by-step explanation:

ok so for the first hour you'd pay 24, so subtract that from the total

60 - 24 = 36

and now to see how many hours you used it after the original  hour, divide 36 by 12

36 ÷ 12 = 3

so you used it for three hours after the original hour

1 + 3 = 4

so you used it for 4 hours in total

hope this helps

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
