We have been given that Nina earns $60 for 5 hours of shoveling snow.
1. Let us find how much Nina earns per hour of shoveling snow.
[tex]\text{Nina earns}=\frac{60\text{ Dollars}}{5\text{ hours}}[/tex]
[tex]\text{Nina earns}=12\frac{\text{ Dollars}}{\text{ hour}}[/tex]
Let us find amount Nina will earn for 6.5 hours of shoveling snow by multiplying 12 by 6.5 .
[tex]12\cdot6.5=78[/tex]
Therefore, Nina will earn $78 for 6.5 hours of shoveling snow.
2. We can find number of hours Nina need to shovel to earn $36 by dividing total amount Nina needs to earn ($36) by amount Nina gets for one hour of snow shoveling ($12).
[tex]\text{Number of hours}=\frac{36}{12}[/tex]
Upon dividing 36 by 12 we will get,
[tex]\text{Number of hours}=3[/tex]
Therefore, Nina will need to shovel snow for 3 hours to earn $36.
6.5 hours for $78
3 hours to earn $36
