Final answer:
To calculate the price for 5 gallons of ice cream when 2 gallons cost $7.22, first determine the cost per gallon, which is $3.61, and then multiply by 5 to get the total cost of $18.05.
Step-by-step explanation:
If 2 gallons of ice cream are on sale for $7.22, finding the price for 5 gallons of ice cream involves a two-step process. First, we need to determine the cost per gallon by dividing the total cost by the number of gallons. Then, we multiply that cost per gallon by the desired number of gallons, which in this case is 5.
The price per gallon can be calculated as follows: $7.22 ÷ 2 gallons = $3.61 per gallon. Now that we have the price per gallon, we can find out the cost for 5 gallons by multiplying $3.61 by 5.
The total cost for 5 gallons would be: $3.61 × 5 = $18.05. Therefore, the price for 5 gallons of ice cream, given the rate of $7.22 for 2 gallons, is $18.05.
