If John starts with \($305\) and then spends 3 dollars a day, John is now losing money from the amount he started with. Since d indicates the amount of days that John is losing money, we can derive the following expression to describe the situation:
 

\(305-3d\)

 

This is the only expression which describes the situation accurately because John begins with 305 and is now subtracting 3 dollars per day. Therefore, the answer is 4th bullet point.

 

9)

 

In this problem, we need to realize that each variable has a different meaning and to which equation does this specific scenario correlate to. We know the following information:

 

\(\text{Sweaters}\hspace{1mm}(s)=28\)

 

With this information alone, we can eliminate the second and 4th answers because the coefficient in front of the s is 14--not 28. Let's keep going. 

 

\(\text{T-shirts}\hspace{1mm}(t)=14\)

 

Since the coefficient of t is 14, we know that the first answer is the only answer that meets both conditions that

 

1) s has a coefficient of 28

2) t has a coefficient of 14

 

Therefore, the answer is A.
