Question

The total weight of a tin and the cookies it contains is 2 pounds. After ¾ of the cookies are eaten, the tin and the remaining cookies weigh 0.8 pounds. What is the weight of the empty tin in pounds?

A. 0.2 
B. 0.3 
C. 0.4 
D. 0.5 
E. 0.6

anonymous · Answer

Weight of tin = x
Weight of cookies (at initial) = y
$$x + y = 2$$
$$x + \frac{y}{4} = 0.8$$
So can you solve for x by yourself?
