Let p be Pancake and BC be butter cookie
1 set of boxes contain 5 BC and 2 P
20x5+22x2=144 sets of boxes
1152/144=8 sets
(a) 5x8=40boxes of BC & 2x8=16 boxes of P
Price of 1BC is 3 units
Price of 1P is 4 units
total amount of BC=40x20=800
total amount of P=16x22=352
money earned from BC=800x3units=2400units
money earned from P=352x4units=1408units
total unit=1408+2400=3808units
3808units=$552
1box=20BC=20x3=60 units
60units=$8.70
