Question

Lorenzo bought several pounds of chocolate-covered peanuts and

gave the cashier a $20 bill. Write an expression for the amount of change he will
receive if p represents the cost of the peanuts

Answer 1

20 - p

So, set up the expression:

20 - p

The expression to represent how much change he will get is 20 - p
