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 inclu
Pepsi [2]

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
