C= 12r + 2
what is c?
what is r?

Unless there is some context behind it, with a picture or something here you are.

Step-by-step explanation:

C=12r+2

So, we have to find out what it could be.

You can plug in anything for r, so I'll make it easy.

r=1

C=12*(1)+2

12*1=12+2=14

C=14.

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:
