Question

You rake leaves to earn extra cash. You charge clients $10 an hour. On average, you work 20 hours a week. You are thinking about increasing your hourly rate by 15%. If you do begin charging your clients more what will be the difference in how much money you earn each week?

Answer 1

In this case the answer is very simple . .

Step 01:

Data

Initial earnings

1 hour ===> $10

20 hours / week

New earnings

+ 15% hour

$10 * (1.15)

Step 02:

Inicial earnings

`\frac{10\text{ \$}}{\text{hour}}\cdot\frac{20\text{ hour}}{\text{week}}=\text{ 200 \$ / we}ek`

New earnings

`\frac{10\cdot\text{ (1.15) \$}}{\text{hour}}\cdot\frac{20\text{ hour}}{\text{week}}\text{ = }230\text{ \$ / w}eek`

The difference would be:

New earnings - Inicial earnings = $ (230 - 200) = $30

The answer is:

The difference in money you will earn is $ 30.
