Each school's rank going into the tournament is a strong indicator of their
likelihood of winning their first game. This
can be expressed as y=-6.14x + 103
where x is their rank (out of 16) and y is
the percent chance they have of winning
their first game.
According to the model, a school ranked #7 has what probability of winning their first game?

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:
