Answer: The total cost in dollars of the gas is $77.80.

Step-by-step explanation:

since we have given that

Amount of gallon of gas he bought for the first time = 12.53

Amount of gallon of gas he bought for the second time = 11.86

According to question, He paid $3.19 per gallon both the times that he stopped for gas on a weekend trip.

So, our expression that shows the total cost in dollars of the gas he bought on this trip is given by

$12.53\times 3.19+11.86\times 3.19\\\\\text{ using distributive law}\\\\=3.19(12.53+11.86)\\\\=\$77.80$

Hence, the total cost in dollars of the gas is $77.80.
