For the next $24$ months after January $2018$, the total number of customers subscribed to the newsletter each month was $7\%$ greater than the total number subscribed the previous month. Which equation gives the total number of customers, $c$, subscribed to the company's newsletter $m$ months after January $2018$, where $m\le 24$?
