Suppose you mark n points on a circle, where n is a whole number greater than 1. the number of segments you can draw that connect these points is 1/2n^2 - 1/2n how many segments can you draw if you mark 8 points on the circle? a. 56 segments b. 32 segments c. 60 segments d. 28 segments

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:
