Question

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.
Enter the expression in the box that represents the price of the television set after the instant rebate is applied and before the tax is applied.

Answer 1

The price of the television set after the instant rebate is applied is x-300.  The tax applied portion of the expression is .07x.  In this case, the instant rebate is $300 and the tax applied would be 7%.  X is the initial cost of the TV before any discounts or taxes are applied.
