Andrew makes $6 an hour plus $9 an hour for every hour of overtime. overtime hours are any hours more than 40 hours for the week. create an equation that shows the amount of wages earned, w, for working x hours in a week when there is no overtimecreate 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. andrew earned $330 in 1 week. how many hours (regular plus overtime) did he work?

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

6/ 11 = 0.545454 so your answer is55%
