What are the values of a and b on the number line? A number line from negative 4 to 4 with marks at halves. Point A is plotted at one mark to the right of negative 2 and point b is plotted halfway between 2 and 4.
A. a = 1.5, b = 2.5
B. a = –1.5, b = 3
C. a = –1.5, b = 2.5
D. a = 1.5, b = 3

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:

something over 10 so ? /10
