Question

Lisa earns $8.10 an hour and worked 40 hours. Jamie earns $10.80 an hour. How many hours would Jamie need to work to equal Lisa’s earnings over 40 hours

Answer 1

30 hours is how much she would work

Answer 2

it takes 30 hours for Jamie to equal Lisa's earnings

Explanation:

Lisa earns $8.10 an hour and worked 40 hours.

Total amount Lisa earns = rate times hours

Total amount Lisa earns =
`8.10 \cdot 40=324`

Jamie earns $10.80 an hour

LEt 'n' be the number of hours Jamie works

Total amount Jamie earns =
`10.80 \cdot n=10.80n`

we need to find out 'n' when Jamie earnings is equal to Lisa earnings

`10.80n= 324`

Divide by 10.80 on both sides

n= 30

So it takes 30 hours for Jamie to equal Lisa's earnings
