5) A Cramer's Rule question: Suppose tickets to a football game are priced according to whether the seat is in the lower-middle of the stands, upper-middle of the stands, or ends of the stadium. The price of two tickets in the lower-middle and one ticket in the upper-middle is $210. The price for one ticket in the lower-middle and two tickets in the upper-middle is $180. The price for one ticket in the upper-middle, one ticket in the lower-middle, and two tickets in an end of the stadium is $190. Let x = the price of a ticket in the lower-middle, y = the price of a ticket in the upper-middle, and z = the price of a ticket in an end of the stadium. If you use Cramer's Rule to find x, y, and z; which one of the following is equal to Dx - Dy + Dz-x+y-z? a) 300 b) 360 c) 240 d) 120 e) 400
