In order to pay for upkeep of a local highway, the transportation department has set up tollbooths at each of the highway’s exits. Drivers are charged a toll of $1.20 for use of the highway, and are then charged an additional $0.04 per mile driven. Write an algebraic expression that can be used to represent the total toll charged if m represents the number of miles driven. What is the toll charged to drive 14 miles on this highway?

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.
