Question

At Greg's Gas Station premium gasoline costs $0.14 more per gallon than regular gasoline . If Mr. Adams spent $36.25 on 12.5 gallons of regular gasoline, how much would Mr. Adams have paid if he bought 12.5 gallons of premium gasoline instead?

Answer 1

Explanation:

At Greg's Gas Station premium gasoline costs $0.14 more per gallon than regular gasoline .

Let the cost of regular gasoline be $x per gallon, then the cost of premium gasoline per gallon will be x + 0.14

If Mr. Adams spent $36.25 on 12.5 gallons of regular gasoline, it means that 12.5x = 36.25

x = 36.25/12.5 = $2.9

The cost of regular gasoline is $2.9 per gallon

Therefore, cost of premium gasoline per gallon will be 2.9+ 0.14 = 3.04

if he bought 12.5 gallons of premium gasoline instead, he would have paid

12.5× 3.04 = $38

The amount that he would have spent more will be

38 - 36.25 = $1.75
