Joan goes to the mall to buy her mom a birthday present. She has $40 to spend. She decides to buy her mom a sweater that costs $35. She picks up a small bracelet that costs $2 for her and goes to the register. Before she reaches the register, she remembers that there is a 9% sales tax. Will Joan be able to buy both items?
In this concept, you will learn to calculate the sales tax.
Calculating Sales Tax
A discount is an amount that is deducted from the original sale price. A sales tax is a percentage of the sales price of an item that is added to a purchase. Most states have a sales tax.
In Maine, the sales tax is 5.5%. If you purchase a book for $25, you will pay $25 plus the sales tax of 5.5%. Find the cost of buying the book in Maine.
First, find the amount of sales tax for a $25 book. Find 5.5% of $25. 5.5% is also 0.055. Multiply $25 by 0.055.
Remember, dollars are rounded to the hundredths place. The sales tax is $1.38. Next, add the sales tax to the original price.
The total price for the book, including the sales tax, is $26.38.
Earlier, you were given a problem about Joan at the mall.
She wants to buy a $35 sweater and a $2 bracelet, but only has $40. To find out if she has enough, she needs to find the sum of the items and the sales tax.

The sales tax is $3.33. Next, add the sales tax to the cost of the items.
The total price is $40.33. Joan will not have enough for both.
