$125 for the car parts,
the labor rate is $68/h
the total estimate is $329
Let's set x to the amount of time (h) that required to fix the car.
Then I was going to pay ($68/h)*xh= $ 68x for the labor.
Let's set up the equation
TOTAL PRICE = LABOR + PARTS
329 = 68x + 125
68x=204
x= 3 h.
I payed for 3 hours of labor.

The admission fee is $3 per person + $6 per person for lunch.
Therefore, each person was going to spend $9 total.
Let's say x (people) can go on the trip. Then ($9/person)*x people is the total expenses + $55 to rent a bus.
We may set up the equation
ALLOWANCE = EXPENSES FOR X PEOPLE + BUS
244 =9x +55
9x=189
x=21
There are 21 people who can go on the trip.
Do you best. Ace the test!!
