Question

I need help with this question, I've been doing it on paper and I still cant get it right.

Drey makes $10 an hour plus $15 an hour for every hour of overtime. Overtime hours are any hours more than 40 hours for the week.

Part A: Create an equation that shows the amount of wages earned, W, for working x hours in a week when there is no overtime.

Part B: Create an equation that shows the amount of wages earned, S, for working y hours of overtime. Hint: Remember to include in the equation the amount earned from working 40 hours.

Part C: Drey earned $490 in 1 week. How many hours (regular plus overtime) did he work?

Answer 1

W = $10(x) where x = number of hours worked

Answer 2

Part B: he has to work 40 hours to get any overtime so:
S = $10(40) + $15(y)

Answer 3

Part C: based on the last equation:

$490 = $10(40) + $15(y)
$490 = $400 + $15y
subtract $400 from both sides to get:
$90 = $15y
divide both sides by $15 to get
y = 4
he worked the normal 40 hours (he couldn't have got paid $400 dollars otherwise) and then he did 4 hrs overtime @ $15 to get $90
