Answer: Choice A
C = 175+0.25n
===============================================
Reason:
n = number of cookies made
0.25n = cost of making all of those n cookies at $0.25 each (aka 25 cents each)
0.25n+175 = add on the initial set up fee and we arrive at the total cost
0.25n+175 is the same as 175+0.25n since the order of adding numbers doesn't matter (eg: 2+3 = 3+2)
---------------
An example:
n = 200 cookies are made
0.25n = 0.25*200 = 50 dollars in cost so far, ignoring the $175 fee
0.25n+175 = 50+175 = 225 dollars total cost after adding on that initial $175 fee
In other words,
C = 0.25n+175
C = 0.25*200+175
C = 50+175
C = 225
Making n = 200 cookies will cost C = 225 dollars.
