A company producing cell phone cases uses either rubber (1x1) or plastic (2x2) with the following production function: =1+23y=x1+x23, where y stands for the number of cases produced, and 1x1 and 2x2 stand for, respectively, the amount of rubber and the amount of plastic used (both in ounces).

Suppose the firm has signed a contract to purchase 200 ounces of rubber. This contract must be honored. Furthermore, the rubber has a very short shelf life if not used for production. That is, if the rubber is not used immediately, it will be wasted. Let 11 be the price of an ounce of rubber, and 22 be the price of an ounce of plastic. Suppose the firm wants to make 290 cell phone cases. The firm's cost of producing 290 cell phone cases equals 29012901 if 1212
