These go together. Now follow these directions: • Your formula in A9 should correctly calculate the Number of People required based on the measurements entered in the Input cells. If I change the numbers in the Input cells change, the output must also change! • Your formula in B9 should correctly calculate the what percentage of the available population will be needed based on the measurements entered in the Input cells. If I change the numbers in the Input cells change, the output must also change! • Your formula in C9 should say “YES” or ”NO” depending on if your available population is large enough to span this length, hand-in-hand. To do this you will use the =IF() function! See if you can figure out how it works!
