Five-Cent Change Calculations

You are helping at a weekend market in Australia. When a customer pays with cash, round the total bill to the nearest 5 cents, then work out the change. Amounts paid electronically are not rounded. Show your working where you can.

Item

Price

Apple

$1.42

Muffin

$2.68

Juice

$3.93

Book

$4.77

Round and reason

Use the Australian cash rounding rule: cents ending in 1 or 2 round down; cents ending in 3 or 4 round up. The same pattern repeats for each ten cents.

1.A customer buys one muffin and pays cash. What amount should the stallholder use as the rounded cash total?

$2.65
$2.68
$2.70
$3.00

2.Using the price board, write the nearest 5-cent cash total for an apple, juice and book, each bought separately.

3.True or false: A cash total of $6.82 rounds down to $6.80.

4.A customer buys an apple and a muffin. Their total before rounding is $. Their rounded cash total is $.

Work out the change

For each cash purchase, round the total first. Then subtract the rounded total from the amount paid.

5.A customer buys a book from the price board and pays with a $10 note. What rounded cash total should be charged, and how much change should the customer receive?

6.Grace buys an apple and a juice and pays with a $10 note. Calculate the total before rounding, the rounded cash total and her change.

7.A customer buys a muffin and pays with $5. The stallholder says, “The rounded total is $2.70, so the change is $2.40.” Is the change correct? Explain or give the correct change.

8.An apple costs $1.42. A customer pays by card. What amount is charged? How would the amount differ if the customer paid cash?

9.Choose any two different items from the price board. Find their total, round it for a cash payment, then work out the change from $10. Show which items you chose.
