Hi there, seems that you need help. I'm going to put these in parts!
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 A: W =6x
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 B: Since without overtime it is 6 $ per hour and you need to make 40 hours
you would multiply 6 *40 = 240
So S = 240 + 9y
Part C: Andrew earned $330 in 1 week. How many hours (regular plus overtime) did he work?
Part C: [Substitute]
Since Andrew earned 330 you would substitute it for S
330 = 240 + 9y <--- solve for y
330 ( - 240 ) = 240 ( - 240 ) 9y < ---- subtract 240 from each side
90 = 9y
90 / 9 = 9y / 9 <----- divide by 9
10 =y Andrew worked 10 hours for overtime
Check
330 = 240 + 9(10)
330 = 240 + 90
330 = 330 <-- your answer is 10
