It might help to think about pseudocode as something you could use to explain what your code is doing to a non-programmer. This means we should use simple words and avoid using too much detail.
I can't solve your problem for you, but here's an example of some pseudocode that would determine how much money was spent on breakfast food over the course of a week:
Variables:
- list of breakfast food names
- total spent on breakfast
- name of current food
- price of current food
Inputs:
GET INPUT What's something you ate this week?
store this input into the name of current food
GET INPUT How much did it cost?
store this input into the price of current food
If the name of the current food is in the list of breakfast foods:
add the price of the current food to the total spent on breakfast
GET INPUT Did you have other food this week?
If the answer is yes:
do it again!
If the answer is no:
OUTPUT the total spent on breakfast
