The labor fee is $13.55 and each quart of oil is $2.25
Step-by-step explanation:
Let,
x be the amount of each quart of oil
y be the amount of labor fee
According to given statement;
5x+y=24.80 Eqn 1
7x+y=29.30 Eqn 2
Subtracting Eqn 1 from Eqn 2

Dividing both sides by 2

Putting x=2.25 in Eqn 1

The labor fee is $13.55 and each quart of oil is $2.25
