If there were p puffs, then
p-16 = 2/3 (91-p)
p-16 = 2/3 (91-p)

number of puffs --- x
number of pies --- y
x + y = 91 -------> y = 91-x
pies sold: 1/3 y, leaving (2/3)y
puffs sold: 16, leaving x - 16
these are supposed to be equal
(2/3)y = x - 16
2y = 3x - 48
y = (3x-48)/2 , sub in y = 91-x
91-x = (3x-48)/2
182 - 2x = 3x - 48
-5x = -230
x = 46 , then y = 91-46 = 45
state your conclusion.
