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

$3.92  per gallon

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

Step-by-step 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

answer: about 22.67
