the first 5 right here the next 5 i will upload as separate question

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.

1.35x+1.08y=104.49.

3. solve the system of two equations:
