Question

Robert earns $8.65 per hour mowing lawns. A) Write a rule for money m as a function of the number of hours h spent mowing lawns. B) How much does Robert earn if she works 3 hours and 25 minutes?

Answer 1

A)
`m=8.65h`

B) $29.58

Explanation:

Earnings per hour = $8.65

To find:

A) Write a rule for money m as a function of the number of hours h spent mowing lawns.

Earnings done in one hour = $8.65

Number of hours =
`h`

To find the total earnings,
`m` as a function of number of hours
`h`, we need to multiply per hour earnings with number of hours
`h`.

Therefore, the equation is:

`m=8.65h`

B) How much does Robert earn if she works 3 hours and 25 minutes?

First of all, let us convert 3 hours and 25 minutes to hours.

3 hours 25 minutes = 3.42 hours

Therefore, total earnings are:

`m = 8.65* 3.42 = \$29.58`
