The expression 0.07x+(x−300) models the final price of a television set with an instant rebate in a state that charges a sales tax. The sales tax is on the original price.
Which expression represents the price of the television set after the instant rebate is applied but before the tax is applied?

The model provided can be broken down into three parts: x is the original price of the television set before any changes were made on it. (x-300) is the price after the instant rebate was applied, and 0.07x is the sales tax (7%) charged by the state. Note this charge is applied on the original price.

Answer: (x-300) is price of the television set after the instant rebate is applied but before the tax is applied.
