The team’s engagement score was 4.80 this month. The score has been improving at a rate of 10% per month. What was the score 5 months ago?

Answer :

Parraingo

Based on the current score and the rate of increase, the score 5 months ago must have been 2.98.

What was the score 5 months ago?

Assume the score 5 months ago was x. This means that the above can be expressed as:

Current score = x × ( 1 + rate) ^ number of months

4.80 = x × (1 + 10%)⁵

4.8 = x × 1.1.61051

x = 4.8 / 1.61051

= 2.980

In conclusion, the score was 2.98.
