Mario Brothers, a game manufacturer, has a new idea for an adventure game. It can either market the game as a traditional board game or as an interactive DVD, but not both. Consider the following cash flows of the two mutually exclusive projects. Assume the discount rate for both projects is 8 percent.

Year	Board Game			DVD
0	$	1,750		$	3,800
1		800			2,300
2		1,500			1,680
3		320			1,350

a. What is the payback period for each project? (Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)
