Each morning Papa notes the birds feeding on his bird feeder. So far this month he has seen 59 blue jays,68 black crows, 12 red robins and 1 cardinal. If 300 birds visit Papa's birdfeeder, how many blue jays can we expect to see?

This question is under Experimental Probability

Step-by-step explanation:

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:

if the probability is 1/12, 75 people will receive a $25 gift card
