I didn't understand your question.
C=1.67n
It's kind of like y=mx+b. C stands for the overall price. And n stands for the amount of pounds. For example if someone bought 6 pounds apples at the farm it would be
c=1.67(6)
c= $10.02
There are 7,315 different combinations, thus, the correct option is c
<h3>
How many combinations are there?</h3>
If we have a set of N elements, the number of different combinations of K elements (such that K ≤ N) of these N elements that we can make is:

In this case we have K = 4 and N = 22, replacing that, we get:

So there are 7,315 different combinations, thus, the correct option is c.
