(02.02 hc) dominic earns $18 an hour plus $25 an hour for every hour of overtime. overtime hours are any hours more than 35 hours for the week. part a: create an equation that shows the amount of money earned, e, for working x hours in a week when there is no overtime. (3 points) part b: create an equation that shows the amount of wages earned, t, for working y hours of overtime. hint: remember to include in the equation the amount earned from working 35 hours. (3 points) part c: dominic earned $730 in 1 week. how many hours (regular plus overtime) did he work? show your work. (4 points) (10 points)

Part A)
Let
E> the amount of money earned
x> hours working in a week> $18 an hour
we know that
E=18x > equation that shows the amount of money earned for working x hours in a week
conditioned to  x<= 35  hours> is no overtime

Part B)
Let
T> the amount of money earned
y > hours of overtime> $25 an hour 
for x=35 hour> E=18*35=$630
T=630+25y> equation that shows the amount of wages earned for working y hours of overtime and 35 hour in a week

Part C) 
if Dominic earned $730 in 1 week
$630> earned for working 35 hours in a regular week 
[hours of overtime]=(730-630)/25=100/25=4 hours

[total hours worked]=35+4=39 hours

the answer is 39 hours  (35 hours regular +4 hours overtime)

Subtracting is the opposite of adding
