Unless you carry a zillion pennies around with you, you rarely have the exact amount of money needed to buy something, so you usually pay more and get change. Learn to figure out the correct amount!
You want to buy an ice cream cone for $5.25, but you only have a ten-dollar bill. Will you get enough change back to buy some candy bars for $1.30 each? If so, how many?
We do not always have the exact amount of money we need.
Sometimes, we will need to get change back or make change. So, how do we find the correct change?
To begin, let’s review adding and subtracting money amounts.
To add and subtract money, we must line up the decimal points. First, we add or subtract the cents, the numbers after the decimal. Then, we add or subtract the dollars, the numbers before the decimal:
$ | 3 | 2 | . | 5 | 0 | $ | 4 | 6 | . | 2 | 0 | ||||
+ | $ | 2 | 1 | . | 4 | 0 | - | $ | 3 | 5 | . | 1 | 0 | ||
$ | 5 | 3 | . | 9 | 0 | $ | 1 | 1 | . | 1 | 0 |
Now, use your addition and subtraction skills to make change.
