[Part1] A linear programming problem has the following two constraints:

(Part SA) If the profit for product X was reduced to $4 (i.e., $5 becomes  $4) while at the same time the profit for product Y was increased to $7 ($4 becomes  $7), what would be the new profit (i.e., the value of the objective function)?
