There are 12 months in a yr so 12/3=4 then 1/3x4=4/3 so 1ft and 1/3 erode each yr. C is the correct answer<span />
Answer: y =13 because y represents how the number of how many times you multiply 2/3 to get to 14/39 so you divide 39 by 3 and get 13. now if you times 2 by 13, you don't get fourteen so I'm confused on that part and I might be wrong so I'm sorry if I'm wrong
Do $15,000x.014x2
--
$15,000x.014=$210
$210x2=$420
