Answer 2

0.6955x

Explanation:

Given the following :

Promotional discount on items = 35%

Sales tax on items = 7%

Original cost of items = x

First we obtain the cost of item after the promotional discount is applied

Cost of item :

Original price - (original price * promotional discount)

x - (x * 0.35) = x - 0.35x

Cost of item = 0.65x

Then the sales tax is added :

Total amount after tax:

Cost of item + (cost of item × sales tax rate)

0.65x + (0.65x * 0.07)

0.65x + 0.0455x

= 0.6955x
