Answer from: Quest
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. together, the classes sold 85 items, then
x+y=85.
2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,
1.35x+1.08y=104.49.
3. solve the system of two equations:
