Question

Dominique buys $14.95 worth of gasoline for her car. If the gas station charges $1.43 per gallon, how many gallons did she get? Round to the nearest tenth.

Answer 1

I'm going to represent this situation as an equation:

x = the number of gallons

y = the total cost

1.42x = y

1.42x = 14.95

[They charge $1.43 per gallon(x), and she payed a total (y) of $14.95]

You need to find the number of gallons or "x".

To do so, you isolate "x" in the equation:

1.42x = 14.95 Divide 1.42 on both sides (or divide 14.95 by 1.42)

x = 10.5 She got 10.5 gallons

Answer 2

$10.45

Explanation:

14.95 divided by 1.43 = 10.50
