Mr. Smith bought shoes for $ 120 and a suit for $ 340. Find the total cost including tax if the tax rate is 5.5%.
(a)$485.30 (b)$48.53 (c)$ 358.70 (d)$460 (e)$406
$460(1.055) = ?
To find the total cost including tax, we need to calculate the tax on the amount spent on shoes and the amount spent on the suit separately, and then add them together.
First, let's calculate the tax on the shoes. The cost of shoes is $120, and the tax rate is 5.5%. To find the tax, multiply the cost of shoes by the tax rate:
Tax on shoes = $120 * 0.055 = $6.60
Next, let's calculate the tax on the suit. The cost of the suit is $340, and the tax rate is 5.5%. To find the tax, multiply the cost of the suit by the tax rate:
Tax on suit = $340 * 0.055 = $18.70
Now, we can find the total cost including tax by adding the cost of the shoes, the cost of the suit, and the taxes:
Total cost including tax = Cost of shoes + Cost of suit + Tax on shoes + Tax on suit
= $120 + $340 + $6.60 + $18.70
= $485.30
Therefore, the correct answer is (a) $485.30.
