KengaRu [80]

Answer:

Total Price = 1.07(0.65x)= 0.6955x.

Step-by-step explanation:

The discount percentage is, <em>d</em>% = 35%.

The sales tax percentage is, <em>s</em>% = 7%.

The variable <em>x</em> represent the original cost of the item(s).

The discount is subtracted from the original amount.

So, the discounted amount will be, 0.65x.

And the sales tax is added to the original amount.

So, the value of tax plus price will be, 1.07x.

Then the final price of the item(s) will be:

Total Price = 1.07(0.65x)= 0.6955x.
