The price of gasoline purchased varies directly as the number of gallons of gas purchased. Suppose 24 gallons are purchased for $94.20. Step 1 of 2: Find the constant of proportionality k, rounded to two decimal places if necessary, and use it to write an equation that models the relationship. Let rrepresent the number of gallons purchased, and let yrepresent the total price. Step 2 of 2: Using the equation from the previous step, find the price of purchasing 34 gallons. Round your answer to two decimal places if necessary.
