Computer modelling uses computers to simulate situations and test how outcomes may differ under various conditions. Models allow changing inputs to see how they affect results without real-world consequences. This document provides an example of a computer model to calculate car sales profits and commissions. The model tracks car prices, sales amounts, profits, and applies a 2% commission rate to total profits. It also includes an IF statement to check if total commissions exceed $500 to determine if sales targets were met.

computer to ‘model’ situations to see how
they are likely to work out if you do different
things.
