After discontinuing all advertising for a tool kit in 2010, the manufacturer noted that sales began to drop according to the model
500,000
S =
1 + 0.1ekt
where S represents the number of units sold and t represents the year, with t = 0 corresponding to 2010 (see figure). In 2014, 300,000 units were sold.
