Mr. Ledger buys a box of 24 donuts for a lesson in his math class about circumference. Write an equation for the number of donuts y that are left at the end of the day when x donuts are used during the lesson.
An equation for the number of donuts y that are left at the end of the day when x donuts are being used during the day is y=24-x. You would subtract x, the number of donuts being used from 24, the total amount of donuts. To get your y.
