Answer 1

The total price for the nails is $ 12.71.

Since at the hardware store, you purchase a box of nails originally worth $ 14.99, and you have a coupon for 20% off the nails, and sales tax is 6%, to determine what is the total cost for the nails, the following calculation must be made:

• Original price - discount + tax = Total price
• (14.99 x 0.8) x 1.06 = X
• 11.992 x 1.06 = X
• 12.71 = X

Therefore, the total price for the nails is $ 12.71.

Answer 2

Sales tax:-6%

Coupon=20%

Net discount=20-6=14%

Total cost

$\\ \sf\longmapsto 14.99-0.14(14.99)$

$\\ \sf\longmapsto 14.99-2.09$

$\\ \sf\longmapsto 12.9$
