Mr. flanders’ class sold doughnuts for $1.35 each and mr. rodriquez’s class sold cartons of milk for $1.08 each. together, the classes sold 85 items and earned $104.49 for their school. how many of each item did the classes sell? define the variables in this situation. write a system of equations that model the problem. use the linear combination method to find the solution to the system you wrote in part b. show all your work! using a complete sentence, explain what the solution found in part c represents.

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:
