Can someone please explain this question

Sure thing!

So if we look at the function, it is an exponential, meaning that it is a number to the power of x
The graph can be described by the equation

y = a^x

If we look at the graph, one of the points on the line is (2, 16), the x value is 2 and the y value is 16

If we consider this along with the function for the graph, we can say that

16 = a^2

Just solve this for a and you’ll have your answer :)

k0ka [10]
The order you apply the adjustments does make a difference because the percents that are applied will be applied to different amount.  

For example, 80% of 100 = $80.  The price would be $180.

Decreasing this by 25% 25% of 180 = $45; 180-45 = $135.  

25% of 100 is not the same as 25% of 180.
