Answer:
They recover <u>43.75 gallons</u> 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:
<u><em>Number of cars the car company changes the oil × Quantity of oil they recover from each car.</em></u>
<u>The car company recovers 175 quarts of oil.</u>
Now, to get the gallons of oil we convert the quarts into gallons by using conversion factor:
<em>1 quart = 0.25 gallon.</em>
<em>175 quarts = 0.25 × 175 gallons.</em>
<em>175 quarts = 43.75 gallons.</em>
Therefore, they recover 43.75 gallons of oil.
