Final answer:
To estimate the annual cost of gasoline, multiply the average monthly cost, $110.74, by the number of months in a year (12) to get $1,328.88. The closest estimate is $1,320, which is option B.
Correct option is B. $1,320
Step-by-step explanation:
To calculate the amount of money Rick spends on gasoline in a year, based on the average amount he spends per month, we need to multiply the monthly cost by the number of months in a year. Rick spends an average of $110.74 per month on gasoline.
There are 12 months in a year, so we multiply:
Annual gasoline cost = Monthly gasoline cost × Number of months in a year
Annual gasoline cost = $110.74 × 12
Annual gasoline cost = $1,328.88
The closest estimate to the actual annual cost is $1,320, which would be option B.
