I am having trouble with this problem.

The Bean Barn needs to grind the beans to make three types of house special coffee blends. There are four types of coffee beans used to make the three blends. The three coffee blends are mellow mocha, regular and java jolt. The four types of beans available are Vietnamese, Columbian, Blue Mountain & Brazilian. Any un- used beans will be used in other products. The requirements for the three coffee blends are as follows: The Blends Blend Mellow Regular Java Jolt Min Pb 4.6 4.6 4.6 Min caffeine % none 1.5% 2.6 % Max caffeine % 1.2 % 2.5% unlimited Max we can sell 100 lbs. 2001bs. 1501bs.
