Question

Each week you drive 150 miles.your car gets 25 miles to the gallon and gas prices are 3 per gallon.how much gas money will you spend on gas each week

Answer 1

You will spend 21 dollars each week

Answer 2

150miles per week
25 miles per gallon
3 dollars per gallon

$\frac{150miles}{1week}* \frac{1 gallon}{25miles}* \frac{3 dollars}{1 gallon} = 18 dollars per week$
(mile and gallons, since the are both on the top and bottom of the fraction cancel out, leaving us with dollars per week)

Answer=$18 per week
