a, price apple pie
p, price pumpkin pie

system%282a%2B2p=56%2C7a%2B14p=301%29

a%2Bp=28------but this is not likely how the question is meant.

7a%2B14p-7%28a%2Bp%29=301-7%2A28------this will give the value for p.

The problem doesn't ask us to find the cost of each apple pie and each pumpkin pie; it only asks us to find the cost of one apple pie and one pumpkin pie.

So divide the first purchase by 2 to find that the cost of one apple pie and one pumpkin pie is $56/2 = $28.

What the problem really asks,  is unknown and can be treated/interpreted differently.

It may ask to find two prices separately or to find the cost of one apple pie and one pumpkin pie altogether -
- from the post,  we don't know the precise meaning of the question.


In human language, there are words that allow to make the question unambiguous.

In this problem, these words are "altogether" or "separately".


Without using these words, the post is not a Math problem - it is a puzzle, instead,
where a reader should guess the meaning of the question.
