Answer:
20,000 customers
Step-by-step explanation:
The campaign initially brought in 10,000 new customers. These 10,000 customers should bring 5,000 more. Then these 5,00 should bring 2,500 more customers and so on. in order to solve this question, we can calculate a customer multiplier = 1 / % of customers who bring additional new customers = 1 / 50% = 2
the total number of new customers = 10,000 x 2 = 20,000
