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?

1 answer

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.
