Question

Define a variable and write an equation for each situation. Solve each equation to answer the question.



A plumber finished three jobs on Tuesday. The first two only cost the owner $45 trip fee because they took very little time to complete. For the third job, the plumber charged the trip fee plus 6 times his hourly rate. If the plumber received a total of $303 for the day, what is the hourly rate?


H = Hourly Rate

for my Equation I made,
5(45)+6h=303

but cant figure out how to solve it

Plz work out the problem, thnx :-)

Answer 1

your equation is wrong

the first is suppoosed to be 3(45), you wrote 5(45) but it should be 3(45), it's 3 trips, not 5


the other part is right tho, it is 6h

so 3(45)+6h=303 is the right equation
remember, you can do anything to an equation as long as you do it to both sides

so first expand 3(45)
3(45)=135

135+6h=303
minus 135 both sides
6h=168
divide both sides by 6
h=28


the hourly rate is $28 per hour
