Step-by-step explanation:

I hope that is useful for you :)
We are going to want to change any mixed number into an improper fraction. 2 3/4 is 11/4 and 1 2/5 is 7/5.
We are going to set up a proportion where the lbs are on the top and the money is on the bottom. x is going to be how much it costs for 2 3/4 lbs of lunch meat.
(7/5)/3.36 = (11/4)/x
Cross multiplication \/
7/5x = 9.24
x = 6.60
As a final answer, the 2 3/4 lbs of lunch meat cost $6.60
B = rw+ r
Factor the right side:
b = r (w + 1)
Divide each side by ' r ' :
b/r = w + 1
Subtract 1 from each side:
b/r - 1 = w
