Worked Examples

Worked Example 1

Making Change

An item costs $3.65. You pay with $5.00. How much change do you get, and what bills and coins could the cashier use?
  1. 1Count up from $3.65: a dime makes $3.75, a quarter makes $4.00, and $1 makes $5.00.
  2. 2$0.10 + $0.25 + $1.00 = $1.35
Answer: $1.35: one $1 bill, a quarter, and a dime

Worked Example 2

Two-Step Problem

You buy a book for $2.49 and a game for $4.75, and pay with a $10 bill. How much change do you get?
  1. 1Total cost: $2.49 + $4.75 = $7.24
  2. 2Change: $10.00 − $7.24 = $2.76
Answer: $2.76

Common Mistakes to Watch For

Not regrouping cents into dollars

Wrong:$2.49 + $4.75 = $6.124

49 cents + 75 cents is 124 cents, which is $1.24. The total is $7.24.

Not regrouping when subtracting from a whole dollar amount

Wrong:$10.00 − $7.24 = $3.24

Regroup $10.00 as $9 + 100 cents: $10.00 − $7.24 = $2.76.

Helpful Math Tip

Let your child pay at the store or check a receipt, and estimate the change before the cashier gives it.
