Paulo tracks his commute time. the coordinate plane below shows some of his commute times in the last two weeks. the xxx-axis of the graph represents the number of days before today. for example, -1−1minus, 1 would represent yesterday. the yyy-axis represents the commute time in minutes. 222 days ago, paulo's commute time was halfway between his commute times 888 and 999 days ago.

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:
