For the first 40 hrs she earns $40 per hr hence she should work for the first 40 hrs. Her income on that would be$1600
For each hr more she will earn $80. Hence, let the extra hrs she works be x then for that she earns 80x. By question, $$\frac{80x + 1600}{40+x} = 60$$ solve for x; x = 40 Therefore, total hrs she has to work for the week to earn$60 avg would be 80 hrs.

Re: Every week, Renee is paid $40 per hour for the first 40 hour [#permalink] 15 Oct 2018, 09:04 Renee makes$40*40 hours=$1600 in first 40 hours Let 't' be the no of hours Renee would work. Given, Renee makes$80 per hour for each hour she works after the first 40 hours. So, she makes an additional pay $80*(t-40)hours for every hour after 40 hours. So, 1600+80(t−40)t=601600+80(t−40)t=60 Or, 1600+80t-3200=60t Or, 20t=1600 or, t=80 hours Ans.
