Since vacation travel is a discretionary expense, consumers want to make the most out of the money they have budgeted. They often check travel websites for
hotel ratings before making any reservations. A popular travel website offers
travelers the opportunity to rate a hotel experience based on five categories:
Excellent, Very Good, Average, Poor, and Terrible. Use the following table to find
what percentage of the ratings were Average, Poor, and Terrible. *

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.
