Answer:
$10.45
Step-by-step explanation:
14.95 divided by 1.43 = 10.50
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
