2) The value of y is directly proportional to the value of x. Given y = 12 when x = 36. What is the value of y when x = 60? Show your work to receive full credit.

20

Step-by-step explanation:

y=12

x=36

Ration x/y is 36/12, equals 3

To find the value of y when x=60, divide 60 by 3, this will give you the value of y

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:
