Question

During the winter, you charge people $12 for going to their house to shovel snow, then $9 for every hour you shovel. Your total pay can be modeled by the equation: y = 12 + 9h If you make $57 in one day, how many hours did you spend shoveling? 15 hours 5 hours3 hours9 hours

Answer 1

we have the following:

`y=12+9h`

y = 57, replacing:

`\begin{gathered} 57=12+9h \\ 57-12=9h \\ 9h=45 \\ h=(45)/(9) \\ h=5 \end{gathered}`

therefore, the answer is 5 hours
