Question

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 ofthe following is equal to (See image)
