Suppose a car repair company changes the oil of 50 cars and they recover an average of 3 1/2 quarts of oil from each car. How many gallons of oil did they recover

They recover 43.75 gallons of oil.

Step-by-step explanation:

A car repair company changes the oil of 50 cars and they recover an average of 3 1/2 quarts of oil from each car.

Now, to find the gallons of oil they recover.

Number of cars the car company changes the oil = 50.

Quantity of oil they recover from each car =

Now, to get the total quantity of oil they recover we multiply number of cars the car company changes the oil by quantity of oil they recover from each car:

Number of cars the car company changes the oil × Quantity of oil they recover from each car.

The car company recovers 175 quarts of oil.

Now, to get the gallons of oil we convert the quarts into gallons by using conversion factor:

1 quart = 0.25 gallon.

175 quarts = 0.25 × 175 gallons.

175 quarts = 43.75 gallons.

Therefore, they recover 43.75 gallons of oil.
