A chemical manufacturer wants to lease a fleet of 22 railroad tank cars with a combined carrying capacity of 312 comma 000 gallons. Tank cars with three different carrying capacities are available: 6 comma 000 gallons, 12 comma 000 gallons, and 24 comma 000 gallons. Letting tequalsnumber of 24 comma 000 railroad tank cars in the fleet, 2tnegative 8 6 comma 000-gallon railroad tank cars, and minus3tplus30 12 comma 000 gallon railroad tank cars will be in the fleet for a certain range of t. The cost of leasing a 6 comma 000-gallon tank car is $250 per month, a 12 comma 000-gallon tank car is $750 per month, and a 24 comma 000-gallon tank car is $1050 per month. Which of the solutions to the number of each type of tank car in the fleet would minimize the monthly leasing cost?

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

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.
