Question

Productivity for a small country was 25 units per worker hour in 2011. Productivity increased 20 percent between 2011 and 2016. What was the productivity figure for 2016? If the rate of increase is maintained, what will the figure be in 2021? In 2026?

Answer 1

525 units

Explanation:

firsat find a 1% increase

25/100 = 0.25

multiply this by 20 (per 5 years) and add to the original amount

0.25 x 20 = 500

500+25 = 525

This is your answer, and you just repeat this process for each year
