    The first one is A. The first inequality 34x+52y<3500 represents the cost of the tables. x+y<50 means that fewer than 50 tables all together are bought.

    The second one is A, C, and E. Just divide the cost by the number of bricks to get the cost per brick. A, C, and E are all $0.74 per brick.
