The cost of a babysitting service on a cruise is $10 for the first hour and $12 for each additional hour. If the total cost of

babysitting baby Aaron was $58, how many hours was Aaron at the sitter?


12x+10=58

10x+12=58

Answer: 12x+10=58

Explanation: $10 is the flat rate, so it only applies to one of the hours. It is not being multiplied by anything. Her hourly rate after that is $12 meanings the amount of money she makes depends on how many hours she works which is x. $58 is the end result so that is what the equation equals.

Answer: Aaron was at the sitter for 5 hours

Explanation:

12x + 10 = 58

the 12x is for each hour after the first hour and the 10 is the first hour

-10 from each side

12x = 48

/12

x = 4

4 additional hours plus the original hour
