5.39-2.20=3.19
3.19 dollars per gallon

Answer 2

Answer:  The required price is $3.19 per gallon.

Step-by-step explanation:  Given that after an oil pipeline burst one morning gas prices went up by $2.20 per gallon. At the afternoon you bought 10 gallons of gas for $53.90.

We are to find the price per gallon before the oil pipeline burst that morning.

We will be using the UNITARY method to solve the given problem.

Cost of 10 gallons of gas = $53.90.

So, the cost of 1 gallon of gas will be

$\dfrac{53.90}{10}=5.39.$

Therefore, in the morning before the oil pipe burst, the cost of 1 gallon of gas is given by

$\ (5.39-2.20)=\ 3.19.$

Thus, the required price is $3.19 per gallon.
