Once we calculate the average number of customers (Total store sales/average spending per person) we can double the customer number to get the no. of customers in 5 years, followed by multiplying it by 20 to get the total store sales after 5 years and dividing it by (2.5*no. of stores presently) to the sales/store
Back to overview

Can't we directly divide the total store sales with average expense per person to determine the number of customers ?

You are right, you can obtain the same result using your way.
You will find a different number just because in the case resolution the intermediate results are rounded.
Hope it helps,
Luca
