Question

At a restaurant you pay $45.00 for a meal but then use a 15% discount coupon. You then need to pay the 8% tax rate.

a) $37.35
b) $39.60
c) $41.25
d) $42.75

Answer 1

To calculate the final amount paid, apply the discount to the initial price, calculate the tax on the discounted price, and add the tax to the discounted price. The tax amount is calculated by multiplying the amount after the discount by the tax percentage.

Step-by-step explanation:

To calculate the final amount paid, we need to follow these steps:

1. Apply the 15% discount to the initial price of $45.00: $45.00 - (15% of $45.00) = $45.00 - $6.75 = $38.25.
2. Calculate the 8% tax on the discounted price: 8% of $38.25 = (8/100) * $38.25 = $3.06.
3. Add the tax to the discounted price to find the final amount: $38.25 + $3.06 = $41.31.

Therefore, the correct answer is c) $41.25. The theory behind the calculations is to first apply the discount to get the reduced cost, and then apply the tax to get the final amount paid. The key steps are multiplication for the discount and tax amounts and addition for the final amount. The tax amount is calculated by multiplying the amount after the discount by the tax percentage. The discount amount is calculated by multiplying the original meal cost by the discount percentage. Subtract the discount amount from the original meal cost to get the amount after the discount.
