You need the revenue of year 2 to calculate what percent you have to increase it to reach 3 million in year 3.
Let R2 be the revenue of year 2 and R3 the revenue of year 3.
The formula of percent increase is:
% increase = ( R3 - R2 ) / R2 *100
=> % increase = (R3 / R2 - 1) * 100
So, given R3 is 3 million
=> % increase = (3,000,000 / R2 - 1) * 100
So, you just have to replace R2 to get the solution.
Let's do one example:
R2 = 2 million
=> % increase = (3,000,000 / 2,000,000 - 1) * 100 = (0.5) * 100 = 50
So, if the revenue of year 2 was 2 million, he needs to increase it 50% to reach 3 million.

It takes 28minutes for 7 people to paint 7 walls. How many minutes does it take 14 people to paint 14 walls?
Answer:
28 minutes
Step-by-step explanation:
It takes 28minutes for 7 people to paint 7 walls.

= 14 walls × 28 people minutes/14 People
= 28 minutes
Therefore, it would take 28 minutes for 14 people to paint 14 walls.
There is a formula for this:
Total Time = (worker1 * worker2) / (worker1 + worker2)
(3 * 8) / (3 + 8)
24 / 11 =
2.1818181818 hours
