Money - Dollars and Cents - Sales Tax - IntoMath

3 years ago

In this lesson you will discover that 1 dollar equals 100 cents and that cents can be expressed as part of a dollar using fractions or decimals ($0.05 = 5 cents).

You will learn and practice how to add and subtract dollars and cents, as well as how to multiply and divide them. For example, if one item costs $2 and 50 cents and the other item costs $3 and 14 cents, what is the total cost of both items? We would add dollars and cents separately and get: $2 + $3 = $5; 50 cents + 14 cents = 64 cents. The total cost is $5 and 64 cents.

The lesson teaches how to group the digits based on their place value in order to do operations with money faster and without a calculator.

It also discusses sales tax and how to calculate it when making a purchase in order to find the grand total. A sales tax is what a customer pays on top of the actual price of the item. In some countries it is included in the price right away, in others it need to be calculated and added at the check out.
