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?

$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

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
