Yolanda created a scatter plot of the relationship between the number of times she visited different friends each month, y, and the distance in miles each friend lives from her home, x. She calculated the equation of the trend line to be y=−3.5x+20. Use this information to predict the number of times in one month Yolanda would visit a friend who lives 4 miles from her home.

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:
