Time-For-US has set up a booth in a shopping mall to sell calendars during the holiday season. The business can purchase the calendars for $2.69 each. It plans to set the unit price at $9.99. During the time it is in business, it must rent equipment for $190 per day, and pay wages of $321 per day. Answer each of the following independant questions

a) How many calendars must the business sell each day to break even? Use this formula: LetXrepresent the volume in units.

To break even,

9.99X - 2.69X - 511 = 0

Solve for X

b) If it decreases the wages to $240.70 per day, how many must it sell each day to break even?

c) If the business puts the calendars "on sale" at 25% off, what would be the profit if it sold 120 units in one day? Using this formula:

Let PFT represent the profit in dollars.

New unit price is 75% of $9.99 = $7.49.

7.49*120 - 2.69*120 - 511 = PFT

d) On the last day the business plans to be in the mall, 200 calendars remain on hand. If the wages for the day are $222, what is the lowest price it can charge for each calendar and still break even for that day?
