Alice earns 2 times her normal hourly rate for each hour she works after 40 hours in a week. She worked 50 hours this week and earned $660.

What is her normal hourly rate?

1 answer

x = Her normal hourly rate

She worked 50 - 40 = 10 hours more of her normal hourly rate.

She earned 40 x for her normal hourly rate + 10 ∙ 2 her normal hourly rate

40 x + 10 ∙ 2 x = 660

40 x + 20 x = 660

60 x = 660

x = 660 / 60

x = $11
