Question

Mr. Autry bought a hat for $99.90. He also bought a pair of boots for $89.90. What was the total cost of the hat and boots including an 8% sales tax

Answer 1

Answer:

$204.98

Step-by-step explanation:

Step 1: Add both item cost

$99.90 + 89.90 = 189.80$

Step 2: Find the sales tax of the result

$\frac{8}{100}\times 189.8 = 15.184$

• Step 1: Convert 8% to fraction
• $8\%= \frac{8}{100}$
• Simplify
• $\frac{8}{100} = \frac{2}{25}$
• Step 2: Convert 189.80 to a fraction
• $189.80 = \frac{189.8}{1}$
• Step 3: Set it up
• $\frac{2}{25}\times \frac{189.8}{1}$
• Step 4: Cross divide
• $189.80 \div 25 = 7.592\\2 \div 1 = 2$
• Step 5: Multiply the result
• $7.592 \times 2 = 15.184$

Step 3: Add the result from the total cost of both items

$189.80 + 15.184 = 204.98$

The total cost of the hats and boots including sales tax is 204.98 dollars
