You are working at a farm that produces cut flowers, and you have been put in charge of a large experiment to understand what promotes the longest-lasting dahlia blooms. You want to examine 4 different refrigeration levels, 4 different water additives (and you'll compare all possible combinations of those additives, from no additives to a mix of some to all four), and 3 different stem treatments. If you need 10 flowers for every possible experimental treatment (fridge+additive+stem), how many flowers total are needed?Help, answer is not 480.
