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?

For the answer to the question above, let us solve the first for
Part A. $10 x 40 hours= $400 ($10x = W) X= 40 hours a week

Part b. $10 x 40 hours = $400 + $15 x Y=S ($10x=$400 +$15y=S) Y= number of hours overtime. Since he gets $15 for working more than 40 hours you take the number of hours over time and multiply it by 15.

Part c.  Now that he made $490 in 1 week you know that he worked for 40 hours at a rate of $10 an hour. But that's only $400, so we need to figure out 15 times what is equal to 90. 15 times six is equal to 90 which means that Drey worked for 46 hours

However, if the workers do outside of what's normally expected, go ahead and tip.
