The martins want to buy a new computer. The regular price is $849.the store is offering 20%discount and a sale tax or 6% is added after the discount. What is the total cost of the TV?

Answer 1

The total cost of the computer after the discount and sales tax is $720.95.

Step-by-step explanation:

To find the total cost of the computer, we need to follow these steps:

1. Calculate the discount amount by multiplying the regular price by the discount rate. In this case, the discount rate is 20%, so the discount amount is $849 * 20% = $169.80.
2. Subtract the discount amount from the regular price to find the discounted price. $849 - $169.80 = $679.20.
3. Calculate the amount of sales tax by multiplying the discounted price by the sales tax rate. In this case, the sales tax rate is 6%, so the sales tax amount is $679.20 * 6% = $40.75.
4. Add the sales tax amount to the discounted price to find the total cost. $679.20 + $40.75 = $720.95.

Therefore, the total cost of the computer after the discount and sales tax is $720.95.

Answer 2

$719.95

Step-by-step explanation:

If the computer is originally $849 and you receive a 20% discount. This means you'll pay 80% of the price since 100-20=80.

To find this price, 80% as 0.8 is multiplied with the price. 0.8*849 = $679.20

This is the sale price.

When you pay you will pay 6% tax or 0.06 of the price. Find this by multiplying $679.20 by 1.06.

679.20(1.06) = 719.95
