If a used car gets 23 mpg and you drive 2000 miles a month what would it cost per year if gas prices remained constant at 2.45/ gallon

Step-by-step explanation:

We first need to figure out how many gallons of gas is being used when you drive 2000 miles per month and the car gets 23 mpg.  Dividing 2000 by 23 tells us that we are using 86.95652174 gallons of gas in 1 month.  Multiply that by 12 to get the number of gallons used in a year, assuming that the number of miles stays constant at 2000 per month.  That gives us 1043.478261 gallons per year.  Multiply that number of gallons per year by the cost of 1 gallon to get that in a year, you would spend $2556.52 in gas.

answer is the third choice:
