At a certain pizzeria, 1/8 of the pizzas sold in one week were mushroom and 1/3 of the remaining pizzas sold were pepperoni. If n of the pizzas sold were pepperoni, how many were mushroom ?

Is the answer 3n/7 ?

1/8 = Mush
remaining = 7/8
1/3 * 7/8 = 7/24
n = 7/24 = 7/3 * (1/8 )
n = 7/3 * Mush
Mush = 3n/7

There is a very simple approach to this problem. Pick a number that the pizzeria is selling. Pick a SMART NUMBER that will cooperate with the given values for both number constraints that are given to you.

ex. you can start with imaginary smart number 24.

1/8 were mushroom = 1/8 of 24 = 3

1/3 of remaining (21) were pepperoni = 7

it also seems that you are missing some information the question answer choices. what is qa and what source is this?

M=1/8
P=1/3*7/8 or 7/24 or n

M=1-all the rest

M=1-3n
