Questions: Nathan buys a bottle of water for 1.25, gum for 0.50, and a book for 3.95. The sales tax is 10%. What is the sales tax for the things he buys?

Solution Steps

First, we need to find the total cost of the items Nathan buys before applying the sales tax. The items and their costs are:

• Bottle of water: \$1.25
• Gum: \$0.50
• Book: \$3.95

Add these amounts together:

\[ 1.25 + 0.50 + 3.95 = 5.70 \]

The sales tax rate is \(10\%\). To find the sales tax amount, multiply the total cost by the sales tax rate:

\[ \text{Sales Tax} = 5.70 \times 0.10 = 0.57 \]
