16800 and i think you meant 1600 in one year
2hrs, 142miles
42x+58=55x+32
13x=26
x=2hrs <---- answer
42*2+58=142
55*2+32=142mi <----answer
The first answer is [7, (infinity symbol) )
the second one is (1, (infinity symbol) )
First we have to find how much they spent on each gallon.
To find out how much Carly paid for each gallon we have to divide her total price by haw many gallons she got.
$17.50/7=$2.50 per gallon
Likewise we do the same for Jade
$45/15=$3
So the answer will be Jade paid more per gallon than Carly
