How to write this as an algorithm or pseudocode?

An algorithm that accepts as input the names of 22 persons attending a conference.Each person falls under one of two categories:
a)Participant
b)Presenter

The algorithm should determine the category in which the attendee falls.The algorithm should also determine the number of attendees who fall under each category.A participant pays a registration fee of $2000.00 and a presenter $1000.00.A listing of category and the total number of persons in each category must be printed ,along with the total amount of money generated in each section.

The simplest way to do this is to use a spreadsheet with columns for Name, Presenter Amount and Participant Amount. By counting the number of entries in each of the amount columns and adding the amount in each payment column, you have your information to print.
