A. Apply the concepts of direct and joint variations in solving thr following problem.

1. Find the constant of variation if y varies jointly as x and z, and y = 105 when x = 7 and z = 3.

2. If y varies jointly as x and z, given y = 12 when x = 5 and z = 15, find y if x = 8 and z = 2.

B. Apply the concepts of direct and joint variations in solving thr following problem.
