Q1) Molly Dymond and Kathleen Taylor are thinking of the possibility of teaching swimming to kids in the summer. Local swim club opens its pool at noon each day, thus it is available to rent in the morning. Cost of renting pool in the 10-week period for which Molly and Kathleen would require it is $1,700. Pool would also charge Molly and Kathleen the admission, towel service, and life guarding fee of= $7 per pupil, and Molly and Kathleen evaluate extra $5 cost per student to hire several assistants. Molly and Kathleen plan to charge $75 per student for the 10-week swimming class.
a) How many pupils do Molly and Kathleen require to enrol in their class to break even?
b) If Molly and Kathleen wishes to make a profit of $5,000 for summer, how many pupils do they require to enrol?
c) Molly and Kathleen evaluate that they might not be able to enrol more than 60 pupils. If they enrol this many pupils, how much would they require to charge per pupil to realize their profit goal of $5,000?
