A)30,70
B)$12650

Let x be the number of TYPE A laser printer bought.
so the number of TYPE B laser printer bought = (100 -x)

profit >= 3450
x*45 + (100 - x)*30 >= 3450
15x >= 450
x >= 30

For minimum cost, TYPE A laser printer should be bought minimum.ie x-->minimum
so, x = 30

TYPE A = 30 and TYPE B = 70

minimum cost = 165*30 + 110*70
=$12650

A)30,70
B)$12650
70*30=2100
30*45=1350 so Atype=30,B type=70
min cost=30*165+70*110=$12650
