a) Produce Visual Basic codes to predict the approximate size of oyster mushroom population. The user should select or enter the starting number of the mushroom in a combo box, enter the average daily population increase (as a percentage) in a text box, and select or enter the number of days the organisms will be left to multiply in another combo box. Then display the result in a listbox as shown by Figure 4.0. For example, assume the user enters the following values: Oyster Mushroom Population Prediction Starting Number 2 Average Daily Increase 30 Number of days to multiply 10 Predict Figure 4.0 Day 1 Approximate Population 2 23456789 2.6000 3.3800 4.3940 5.7122 7.4259 9.6536 12.5497 16.3146 10 21.2090 (10 marks)
