The carpeting you want to purchase costs $2.25 per square foot. How much will it cost you to buy carpet for the room labeled “carpeted floor” in the diagram below?

The image cannot be opened without authentication which is not available.

The area of the title floor is 12ft*12 ft= 144sq. ft. and the area of the carpet floor is 20ft*20ft = 400sq.ft.

If the area cof the room labeled “carpeted floor” is,

(a) 400 sq.ft, the cost of carpet is $ 2.25 *400 = $900;

(b) 144 sq.ft.,the cost of carpet is $ 2.25 *144 = $324

(c) 400-144 = 256 sq.ft, then the cost of carpet is $ 2.25 *256 = $576

step-by-step explanation:

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.
