Question

Johnathan makes $27 per hour and works 25 hours per week. Every week, he has to sell 20 items. If he sells more than 20 items in a week, he receives a commission of 14% on each set of additional 5 items he sells. This week he worked for 25 hours, he sold 25 items, and he made $1,000 in sales beyond the required 20 items. Which equation will help Johnathan to compute this weeks income?

Answer 1

Total income = 27
`*` 25 + 14% of $1000= $815

Explanation:

Number of hours for which Johnathan worked = 25

Salary for each hour = $27

So, income for 25 hours = 25
`*` 27 = $675

Now, it is given that he has sold 25 items.

Sales made beyond the 20 items = $1000

Additional income for additional sales = 14% on each set of 5 items

He has sold exactly 5 additional items that means 1 set of 5 additional items.

So, Additional income for additional sales = 14%
`*` 1000 = $140

Therefore, total income of this week = Income for 25 hours + Income due to additional sales of 5 items

Therefore Total income = 27
`*` 25 + 14% of $1000= $815
