Maximize p = 6x + 9y + 3.3z + 12w subject to

(a) 1.2x + y + z + w ≤ 121.5

(b) 2.2x + y − z − w ≥ 30

(c) 1.2x + y + z + 1.2w ≥ 31.5

(d) x ≥ 0, y ≥ 0, z ≥ 0, w ≥ 0.

Round all answers to two decimal places.

The sum of the first eight terms of an arithmetic progression is 9m + 14. the fifth term of the06 progression is 2m - 6, where m is a constant.given that the first term of the progression is 26,find the value of the common difference, d and thevalue of m.
