Question

The Carson’s are on a road trip they paid $62.70 for 16 1/2 gallons of gasoline

Part 1-Find the price of gasoline per gallon show your work
Part 2-Give an example of a cost and amount that would make the gasoline have a rate of $3.49 per gallon

Answer 1

$3.92 per gallon

10 gallons of gas at $3.49 a gallon will cost $34.90

Explanation:

To find the price per gallon, we take the total cost, and divide by the number of gallons. I will change 16 1/2 to a decimal for ease of math calculations.

16 1/2 = 16.5

cost/gallons

$62.70/16.5

3.91875

Since we are working with money, we round to the nearest cent

$3.92 per gallon

To find the total cost, we multiply the cost per gallon times the number of gallons. We have a cost per gallon of $3.49. If we multiply by 10 gallons

cost = $3.49 * 10

$34.90

10 gallons of gas at $3.49 a gallon will cost $34.90
