Question

Simone earns $ 35 a day at her job, plus $ 4 per hour of overtime. If she made $55 for one day's work, how many hours of overtime did she work

Answer 1

$ 35 a day
$ 4 per hour
These are our key phrases.
We can even start with 55=35+x
55-35=20
20/4=5She worked 5 hours of overtime.

Answer 2

Firstly we need to subtract the amount she earns from normal hours to be left with the amount she earned from overtime.
$55 - $35 = $20.

If Simone earns $4 for one hour of overtime, we can find out how many hours she worked by dividing $20 by $4.
20÷4 = 5

Therefore, Simone worked for 5 hours of overtime.
