Answer:

3.45g + 2.41q = 50

Explanations:

Price of one gallon of gas = $3.45

Price of one quart of oil = $2.41

Number of gallons of gas bought = g

Number of quarts of oil bought = q

Total amount spent = $50

Total amount of gas bought = (Price of one gallon of gas) x (Number of gallons of gas bought)

Total amount of gas bought = 3.45g

Total amount of oil bought = (Price of one quart of oil) x (Number of quarts of oil bought)

Total amount of oil bought = 2.41q

Total amount of gas bought + Total amount of oil bought = Total amount spent

3.45g + 2.41q = 50

Therefore, the required equation is:

3.45g + 2.41q = 50
