Please, please help!! Emerson purchased a game that was on sale for 18% off. The sales tax in his county is 8%. Let y represent the original price of the game. Write an expression that can be used to determine the final cost of the game.

(y-0.18y) + 0.08y

Step-by-step explanation:

(y-0.18y) + 0.08y

Step-by-step explanation:

15 sides

Step-by-step explanation:

Always the sum of interior angle and exterior angle = 180

Let the exterior angle = x

Interior angle = 6.5 *x = 6.5x

x + 6.5x = 180

7.5x = 180

     x = 180/7.5

     x = 24

Exterior angle = 24°

Sum of exterior angles of any polygon = 360

number of side = Sum of exterior angles ÷ measure of each exterior angle

                         = 360 ÷ 24

                        = 15
