Answer 2

Answer:

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

Step-by-step 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
