Find the Number of Apples that have Fallen from the Tree
Problem Statement:
Initially there are 13 apples in a tree by the lake. Some of the apples fall into the lake and 7 remain in the tree. Use the Draw Apple function to draw the correct number of apples in the lake, then run the program and answer the prompt. (Hint: Write an equation using a variable for the number of apples in the lake and solve for the variable)
