What is the interquartile range of this data set? 1, 4, 10, 11, 29, 40, 42, 61, 65, 84, 91 A. 55 B. 65 C. 40 D. 10

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.
