Answer: 7.80%
Explanation:
At the end of 2016, Josh received a dividend of $1.37 and at the end of 2020, he received one of $1.85.
You can calculate the growth rate with the formula:
Dividend Growth Rate = (Dividend received at end of 2020/Dividend received at end of 2016) ^ (1/n) - 1
2016 to 2020 is 4 years.
Dividend growth rate = (1.85 / 1.37)¹/⁴ - 1
= 0.07798518
= 7.80%
