  • ∗ Coming up with the idea for Ocean and History Bike Tours was only the first step for the five friends in starting their business. They have other important plans to make as well. Many of these plans involve questions about money. What will it cost to operate the tours? How much should customers be charged? What profit will be left when all the bills are paid?

  • 3.1 Renting Bicycles The tour operators decided to rent bicycles for their customers rather than having customers bring their own bikes. They called two bike shops and asked for estimates of rental fees.
  • Rocky’s Cycle Center # of bikes Rental fee ($$) 5 400 10 535 15 655 20 770 25 875 30 975 35 1070 40 1140 45 1180 50 1200 Adrian’s Bike Shop

  • 3.2 Finding Customers Sidney, Liz, Celia, Malcolm, and Theo had a route planned and a bike shop chosen. Now they needed customers. They had to figure out what price to charge so they could attract customers and make a profit. To help set a price, the partners did some market research. They obtained a list of people who had taken other bicycle tours and asked 100 of them which of the following amounts they would be willing to pay for the Ocean and History Bike Tour: $150, $200, $250, $300, $350, $400, $450, $500, $550, $600.

  • 3.3 Predicting Profit Based on the results of their survey, the tour operators decided to charge $350 per person for the tour. Of course, not all of this money would be profit. To estimate their profit, they had to consider the expenses involved in running the tour. Sidney estimated these expenses and calculated the expected profit for various numbers of customers. She made a graph to present her predictions to her partners. Since the profit depends on the number of tour customers, she put the number of customers on the x- axis.
