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!!
