Final answer:
To calculate the total cost of the trip to the gas station, multiply 11 gallons of gas by $1.89 per gallon to get $20.79, then add the cost of a soda, $1.79, for a total cost of $22.58.
Step-by-step explanation:
The question asks about calculating the total cost of a trip to the gas station, where the student fills up the car with gasoline at $1.89 per gallon and also plans to buy a soda for $1.79. To find the total cost, the student needs to multiply the number of gallons of gas filled, which is 11, by the cost per gallon, and then add the cost of the soda. Here is how the calculation is done step by step:
- Calculate the cost of gasoline: 11 gallons × $1.89 per gallon = $20.79.
- Add the cost of the soda: $20.79 + $1.79 = $22.58.
Therefore, the total cost for the trip is $22.58.
