Answer:
The labor fee is $14.25, each quart of oil costs $2.25.
Step-by-step explanation:
Let $x be thee price of each quart of oil and $y be a flat fee for labor.
1. If the oil change for one car required 5 quarts of oil, then these 5 quarts cost $5x and together with a flat fee for labor it cost $25.50. Thus,
5x+y=25.50.
2. If the oil change for another car required 7 quarts of oil, then these 7 quarts cost $7x and together with a flat fee for labor it cost $30.00. Thus,
7x+y=30.00.
3. Subtract from the second equation the first one, then
Substitute it into the first equation:
The labor fee is $14.25, each quart of oil costs $2.25.

Hi!
We know she makes $32,000 a year, but we need to know how much she makes in a week. Which leads us to the question,"How many weeks are in a year?".
There are about 52 weeks in a year.
To found out how much money she makes per week, divide.
money per week
32000/52 = 615.384615
I'm not sure if they want you to round up, or round down, or what, but the exact answer is 615.384615.
Hope this helps! :) -Peredhel
