Jessica has a small workshop in her garage to build bookcases. She makes two sizes, 4-shelved (x) and 2-shelved (y). Her profit for the 4-shelved is $50, while her profit on the 2-shelved is $20. It takes
Jessica 4 hours to make the larger one and only 2 hours to build the smaller one. She can only spend
20 hours a week at her hobby, and she needs to build at least two of each size each week for her booth
at the Swap Meet. How many of each size should she build for maximum profit? How much profit
would that be?

Find x & pleeeeaaaassseeee me !
