Question

- Ms. McNeil buys 2.4 gallons of gasoline. The total cost is $7.56. The

equation 2.4p = 7.56 can be used to find the price p in dollars of
one gallon of gasoline. What is the price of one gallon of gasoline?

Answer 1

The price of one gallon of gasoline is $3.15

Explanation:

If the lady buys 2.4 gallons of gasoline for a total of $7.56, then as the problem suggests, one can find the unknown price of gasoline per gallon (p) by solving the equation for the unknown "p":

2.4 p = 7.56

then divide both sides by 2.4 to isolate the unknown "" on one side of the equal sign:

p = 7.56/2.4

p = $3.15

so this is the price per gallon of gasoline.
