Quizplus · Accepted Answer

To find the cost to fill the tank in 1985, first calculate the cost per gallon in 2000 by dividing the total cost by the price per gallon in 2000: $16.19 / 155.0 cents = about 10.45 gallons. Then, to find the cost in 1985, multiply the number of gallons by the price per gallon in 1985: 10.45 gallons * 119.6 cents = about $12.49.
