Pseudocode to compute the unit price for products sold

The following problem can be solved by a program that performs three basic tasks—Input Data, Process Data, and Output Results. Use pseudocode to design a suitable program for solving it. * The manager of the Super Supermarket would like to be able to compute the unit price for products sold there.

Design a program that models the worm’s behavior in the following scenario

• Resource: Ch. 4 in Extended Prelude to Programming: Concepts and Design (2nd ed.) • Design a program that models the worm’s behavior in the following scenario: A worm is moving toward an apple. Each time it moves, the worm cuts the distance between itself and the apple by its own body length until the worm is close enough to enter the apple. The worm can enter the apple when it is within a body length of the apple. I am only looking for pseudocode.
