TVM Question

A company’s annual sales figures over the last four years are as follows: $2.6 million; $3.1 million, $5.3 million, $7.0 million. The firm’s compound annual growth rate over the period is closest to

28% 39% 56%

The solution uses 3 years to calculate the growth rate and hence the answer is 39%

I’m not understanding why itsn’t 4 years. Could someone kindly explain this to me.

The question is asking about the CHANGE.

Period 1 : 2.6M => 3.1M = 19.23%

Period 2 : 3.1M => 5.3M = 70.97%

Period 3 : 5.3M => 7M = 32.08%

Therefore, the annual growth rate is :

=> [((7M/2.6M)1/3)-1] = 39.11%

thank you for the detailed explanation,I was able to follow thanks to you :slight_smile:
