Jason works as a salesperson at a car dealership. He needs to sell 15 cars this month to earn a big bonus. He knows based on historical averages, that for every 25 telephone calls he makes to potential customers, he gets one person to come into the car dealership to look at new cars. And for every two customers that come into the car dealership, one will buy a car. Based on these average numbers, how many telephone calls would Jason need to make to sell 15 cars and earn his bonus?

Step 1: Determine customers needed per car

We are given that for every two customers who come into the dealership, one will buy a car. This means to sell one car, Jason needs to have 2 customers visit the dealership.

Step 2: Calculate total customers needed

Jason needs to sell 15 cars. Since each car requires 2 customers to visit, we multiply the number of cars by the number of customers per car to find the total number of customers Jason needs to attract to the dealership.

Step 3: Determine calls needed per customer

The problem states that for every 25 telephone calls Jason makes, he gets one person to come into the car dealership. Therefore, 25 calls are needed for each customer visit.

Step 4: Calculate total telephone calls needed

We know that Jason needs 30 customers to visit the dealership to sell 15 cars. Since each customer visit requires 25 telephone calls, we multiply the total customers needed by the calls per customer to find the total number of calls Jason must make.
