A) How many cheesecakes did Baker Lam bake at first?
B)Baker Lam decided to deliver the remaining cakes to 4 charity homes. How many cakes did each home receive?

if there were c cheesecakes and m mangocakes,

c/m = 3/2
(c-144)/m = 3/5

c = 240
m = 160

check:
240/160 = 3/2
96/160 = 3/5

after the sales, there were 96+160 = 256 cakes

divide that by 4 to get the number for each home.
