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

Respuesta :

we have the following:

[tex]y=12+9h[/tex]

y = 57, replacing:

[tex]\begin{gathered} 57=12+9h \\ 57-12=9h \\ 9h=45 \\ h=\frac{45}{9} \\ h=5 \end{gathered}[/tex]

therefore, the answer is 5 hours
