You are purchasing a T. V for $990 T. V with 9% sales tax. What is the final price of the T. V.?

The final price of the T.V. is $1,079.10.

Using this formula

Final price=Selling price +(Selling price× Sales tax)

Where:

Selling price=$990

Sales tax=9%

Let plug in the formula

Final price=$990+($990×9%)

Final price=$990+$89.1

Final price=$1,079.10

Inconclusion the final price of the T.V. is $1,079.10.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
