Your mom's new car gets 32 miles per gallon and gasoline costs $1.99 per gallon. You are going to see Uncle buck for Christmas,
Mashcka [7]

The gas cost will be $19.53 for this trip.

Step-by-step explanation:

Given,

Distance covered by car per gallon = 32 miles

Cost of one gallon = $1.99

Unit rate in terms of miles;

32 miles = $1.99

1 mile = \frac{1.99}{32}\ Dollars

Therefore,

314 miles = Unit rate of mile * 314 miles

314 miles = \frac{1.99}{32}*314

314\ miles = \frac{624.86}{32}\\\\314\ miles=\$19.526

Rounding off to nearest hundredth;

314 miles = $19.53

The gas cost will be $19.53 for this trip.
