Final answer:
The data given appears to relate to a potential word problem where a company charges different prices per gallon for different quantities. One could calculate the total cost for each quantity by multiplying the price per gallon by the total gallons. For instance, $2.20 per gallon for 720 million gallons would yield a total of $1.584 billion.
Step-by-step explanation:
Without a clear question, it's a bit difficult to provide a definitive answer, but it seems like these values could relate to a problem involving price per gallon and total gallons. For instance, if the student is trying to calculate the total cost for different amounts of gallons at various prices, they might be using the formulas listed.
One way to interpret this could be in the context of a word problem. Suppose a company sells water in bulk. They alter their price per gallon based on the quantity that the customer purchases. In this case, the figures listed denote the price and total volume for each tier.
For example, if a customer purchases 720 million gallons, the company charges $2.20 per gallon. Therefore, the total cost in this scenario would be $2.20 * 720 million = $1.584 billion. This process can be repeated for each of the listed prices and quantities.
