Question

Nina earns $60 for 5 hours of shoveling snow.

Complete each statement if Nina keeps earning her money at this same rate.For 6.5 hours of shoveling snow, Nina will earn ?

Answer 1

Nina will earn $78

Explanation:

Given:

Nina earns $60 = 5 hours

If Nina shovels 6.5 hours = $?

Solve:

Based on the given we can make a proportion:

`\mathrm{(\$60)/(5\;Hours) =(\$x)/(6.5\;Hours) }`

Using the proportion to solve;

Multiply Cross:

60 × 6.5 = 390

5 × x = 5x

Divide both sides by 5 ⇒ 390 = 5x

390/5 = 5x/5

x = 78

Hence, Nina earns $78 in 6.5 hours.

Check Answer:

60/5 = 12

Thus, Nina earns $12 in one hour.

So, 12 × 6 = 72

Since, 1 hours = $12.. Then 1/2 hours = $12/2 which is $6.

72 + 6 = 78

x = 78
