Question

Joe earns $425 a week for working 40 hours and an additional $20 an hour for each hour over 40. Last week, Joe made $485. Write and solve an equation to determine how many hours over 40 he worked. (Don't forget to define your variable and answer in a complete sentence.) How many total hours did Joe work last week?

Answer 1

Joe worked 3 hours overtime.

Explanation:

Let t = number of hours overworked

425 + 20 × t = 485

425 + 20t = 485

20t = 485 - 425

= 60

`(20t)/(20) = (60)/(20)`

t = 3

`\therefore` Joe worked 3 hours over time.

Hope this helps :)
