Question

Maria charges a $10 base fee, plus $15 per hour for babysitting.

Which equation can be used to find h, the number of hours of babysitting that Maria will charge $160?

Answer 1

To find \( h \), the number of hours of babysitting that Maria will charge $160, we can set up the equation based on her pricing structure.

Maria has a base fee of $10 and charges an additional $15 per hour. The total cost can be expressed with the equation:

\[
\text{Total Cost} = \text{Base Fee} + (\text{Hourly Rate} \times \text{Number of Hours})
\]

Substituting in the values:

\[
160 = 10 + 15h
\]

This equation can be used to find \( h \), the number of hours of babysitting that will result in a total charge of $160.
