Question

kest kuy is offering a sale on its laptop computers with a 20 percent discount off its original price. there is 8% sales tax added to the discounted price to get the final price of the computer. if x is the original price and y is the final price, write an equation to determine the final price based upon the original price.

Answer 1

`y = 0.88x`

Explanation:

Given

`Discount = 20\%`

`Sales\ Tax = 8\%`

Required

Determine the final price

First, we need to determine the sales price after the discount.

`Discount = 20\% * x`

`Discount = 0.20 * x`

`Discount = 0.20x`

`Sales\ Price = x - Discount`

`Sales\ Price = x - 0.20x`

`Sales\ Price = 0.80x`

Next, is to determine the sales tax.

`Sales\ Tax = 8\% * x`

`Sales\ Tax = 0.08 * x`

`Sales\ Tax = 0.08x`

Final Price, y is then calculated as thus:

`y = Sales\ Price + Sales\ Tax`

`y = 0.80x + 0.08x`

`y = 0.88x`
