Jalyn plans to sell algebra nation t-shirts as a fundraiser for a new scholarship initiative. the wholesale t-shirt company charges jalyn $10.00 a shirt for 75 shirts or less. if the number of t-shirts purchased is between 76 and 150 shirts, the company will lower its price to $7.50 per shirt. if jalyn purchases 150 or more shirts, the price will decrease to $6.00 per shirt. which of the following statements are true? select all that apply.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

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.
