1. The increase in the estimated number of users in Company Z from Year 1 to 9 accounts for approximately _____ % of the increase in the estimated number of users across all of Holding Company A's web properties.
Increase in the estimated number of users in Company Z from year 1 to year 9: 99 million (It's 100 mn in year 9 and ~1mn in year 1) = 99 mn => 0.099 billion
increase in the estimated number of users across all of Holding Company A's web properties: 2.8bn - 1bn = 1.8bn (This is given to us)
We need to see 0.099 is what percent of 1.8
Say 0.099 is x% of 1.8=> 0.099 = (x/100)*1.8 => x = 9.9/1.8 => 99/18 => 11/2 => 5.5 = ~5.6
2. In Year 9, the estimated number of users cumulatively across Companies X, Y, and Z was
____ of the estimated users across all of Holding Company A's web properties.
In year 9, we can add all the heights of the bars to get us the estimated number of users across companies X,Y and Z: 800 + (~200) + 100 => 1.1bn
Estimated users across all of Holding Company A's web properties in year 9 = 2.8bn (This is given to us)
Again we need to find 1.1 is what % of 2.8
We know 50% of 2.8 is 1.4 and 1.1 is less than that so the only valid choice is "Between 30 and 50%"
