Answer:
16n.
Step-by-step explanation:
You multiply the cost of 1, $16 by the amount bought "n".
$15 because a mean would allow him to spend $250 over the five months BUT he has already spent $235.
$250 - $235 = $15
Set up a proportion:
8/3 = 72/x
cross multiply then simplify
8/3 = 72/x --> 8x=216 --> divide by 8 --> x= 27 caesars
