Shown as new equation that includes (original + new customer base)

n3=15264a

Explanation:

First we have to find original amount of customers as 3 represents a multiple of n

n3=13824a

n3 means n x 3 then customer base is one third

= 1/3 x 13,824 = 4608 original customers per year

= 4608 original customers +480 new customers

4608 + 480 = 5088 total orig+initial customers

5088 x 3 = 15264 cost

= ($)15,264 cost

new equation

n3=15264a
