Question

Just need to know the answer this is due in like 30 mins

Answer 1

In order to find the value that each one charges, not including extra fees, we need to subtract the fees from the total value that each one charges, and then divide the result by the number of hours to find the values charged per unit hour.

Step 1

Find the values, in dollars, charged per unit hour:

`\begin{gathered} \text{Mia : }(34-10)/(3)=(24)/(3)=8 \\ \\ \text{Alex : }(66-12)/(6)=(54)/(6)=9 \\ \\ \text{Sam : }(92-8)/(7)=(84)/(7)=12 \\ \\ \text{Tony : }(52.5-0)/(3.5)=15 \\ \\ \text{Rene : }(112-2)/(5.5)=(110)/(5.5)=20 \end{gathered}`

Step 2

Identify the babysitters that charge less than $10 per hour. Since only 8 and 10 are less than 10, only the first two babysitters charge less than $10 per hour (not including extra fees).

Answer

Therefore, the babysitters that would charge less than $10 per hour are Mia and Alex (options A and B).
