The final price of the item is $22,644
The initial discount of 10% leaves the price at 90% of the retail value:
cross multiply to solve for x:
100x = 3,060,000
x = 30,600
This new price is then discounted 26%, which means the final price is 74% of $30,600:
cross multiply to solve for x:
100x = 2,264,400
x = 22,644

By using the information given on the graph, we can see that a = 3.
<h3>How to find the value of a?</h3>
Here we have an exponential of the form:
And by looking at the graph, it passes through (0, 4) and (2, 36), so we can write:
From the first equation we get that p = 4, replacing that on the second one we get:
So we conclude that a = 3.
