Answer:

Step-by-step explanation:
We are given that:
First term (a) = 5
common ratio (r) =
The nth term of a geometric sequence is given as:

Since the price is increasing by percentage, rather than a constant rate, we will be using the exponential equation format, which is y=ab^x (a = initial value, b = growth/decay)
Since the value was $590 in the year 2000, 590 will be our a variable.
Since the value is *increasing* by 35%, add 1 and 0.35 (35% in decimal form) together to get 1.35. 1.35 is going to be your b variable.
Putting our equation together, our equation is f(x) = 590(1.35)^x
A, because in order to find the price for each unit you must divide the total price by the number of units bought and 9p=54.90 you would end up dividing both sides by nine which would then get you to find the price of each unit
