Calculation of break-even.
Molly Dymond and Kathleen Taylor are considering the probability of teaching swimming to kids during the summer. A local swim club opens its pool at noon each day, so it is available to rent during the morning. The cost of renting the pool during the 10-week period for which Molly and Kathleen would need it is $1,700. The pool would also charge Molly and Kathleen an admission towel service, and life guarding fee of $7 per purpil, and Molly and kathleen estimate an aditional $5 cost per student to hire several assistants. Molly and Katheleen plan to charge $75 per student for the 10-week swimming class.
a. How many pupils do Molly and Kathleen need to enroll in their class to break even?
b. If Molly and Kathleen want to make a profit of $5,000 for the summer, how many pupils do they need to enroll?
