The stadium vending machine finds that sales of hot dogs average 50,000 hot dogs per game when the hot dogs sell for $2.50 each. for each 50 cent increase in the price, the sales per game drop by 5000 hot dogs. what price per hot dog should the vending company charge to realize the maximum revenue. round to the nearest cent.

a. $2.50
b. $4.00
c. $3.75
d. $5.00

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.
