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 =[tex]8.10 \cdot 40=324[/tex]
Jamie earns $10.80 an hour
LEt 'n' be the number of hours Jamie works
Total amount Jamie earns =[tex]10.80 \cdot n=10.80n[/tex]
we need to find out 'n' when Jamie earnings is equal to Lisa earnings
[tex]10.80n= 324[/tex]
Divide by 10.80 on both sides
n= 30
So it takes 30 hours for Jamie to equal Lisa's earnings
