<h2>Answer:</h2>

The first option is the correct answer.

Step-by-step explanation:

Cost of per gallon of gas = $3.19

Amount of gas purchased on first trip = 12.53 gallons

Amount of gas purchased on second trip = 11.86 gallons

The expression that shows the total cost in dollars of the gas Demarco bought on this trip is :

Total cost = $3.19(12.53+11.86)$

If you want to solve it, the answer comes $77.80
