Question

Joel wants to buy a new tablet computer from a store having a 20% off sale on all tablets. The tablet he wants has an original cost of $190. He also wants to make sure he has enough money to pay the 5% sales tax. How much will Joel pay for the tablet?

Answer 1

He will pay $166.95

You take the original asking price ($190) you find 20% of 190 which is 38. Then you subtract 38 from 190 you get 152. Next you do 5% of 152 and you get 7.95. Finally you add 7.95 to 152 and you get 166.95.

Answer 2

161.5 $

Explanation:

the cost of table after the discount = 100% - 20% = 80%

the cost of table after the discount = Original cost × 80%

=(190)(0.8)

=152 $

the cost of table after the discount plus the tax = (the cost of table after the discount) + (Original cost × 5%)

=152+(190)(0.05)

=152+9.5

=161.5 $

So... The total amount will Joel pay for the tablet = 161.5 $
