I thought you were going to ask: "Write the equation to find the number of days between filling the tank and needing to fill it again." But just then, OOPS!, the equation appeared, and you asked "What can you use this equation for?"

By solving this equation for the variable ' d ', you learn how many days after you fill the tank you'll have to send somebody back to fill it again.
