Explanation:

We are given that an expression models the final price of television set with an instant rebate in a state that charges a sales tax.

`0.07x+(x-300)`

The sale tax in on the original price .

We have to find an expression that represents the price of the television set after the instant rebate is applied but before the tax is applied.

Let x be the original price of television.

Instant rebate is subtracted from original price x.

Then , the cost of the television set=x-300

In the given expression 0.07 x is sales tax. where tax is 7 % on the original price x.

Sales tax is added to the price of television set.
