Detroit Disk, Inc. is a retailer for digital video disks. The projected net income for the current year is $1,840,000 based on a sales volume of 240,000 video disks. Detroit Disk has been selling the disks for $18.00 each. The variable costs consist of the $6.00 unit purchase price of the disks and a handling cost of $2.00 per disk. Detroit Disks annual fixed costs are $560,000. Management is planning for the coming year, when it expects that the unit purchase price of the video disks will increase 30 percent. (Ignore income taxes.)

Question: In order to cover a 30 percent increase in the disks purchase price for the coming year and still maintain the current contribution-margin ratio, what selling price per disk must Detroit Disk establish for the coming year? Please show calculations.

(Do not round intermediate calculations and round your final answer to 2 decimal places.)
