Answer:
Explanation:
Let nâ and nâ be the number of set produced of model A and B per day .
nâ + nâ = 60
20 < nâ < 60
10 < nâ < 40
Total profit Q = 45 nâ + 55 nâ = 45 nâ + 55 ( 60 - nâ )
Q = 3300 - 10 nâ
So to maximise total profit nâ needs to be minimum . The minimum value of nâ = 20
Q = 3300 - 10 x 20
= $ 3100 Â
So model A should be produced 20 and model B should be produced 40 sets .
