The zoo is expecting a new alligator to arrive in a few days. The previous Reptile Chef fed other species of reptiles currently at the zoo according to the information in the table. You speak with the Mammal Chef, who uses the formula y = 72m3/4 to determine the daily calorie intake for the mammals, where y is the number of Calories eaten and m is the mammal's mass in kilograms. You wonder if a similar formula might help determine the number of calories for the new alligator. Substitute the data pairs from the table into the formula to find a number a so that the expression ya = am 3/4 gives the daily number of Calories required by a reptile with a mass of m kilograms. If alligator has a mass of 400 kilograms, how many calories will it require per day?​
