Could someone please help me with this question?

The Rosa model of Mohave Corp. is currently manufactured as a very plain umbrella with no decoration. The company is considering changing this product to a much more decorative model by adding a silk-screened design and embellishments. A summary of the expected costs and revenues for Mohaves two options follows:

Rosa Umbrella			Decorated Umbrella
Estimated demand		17,000	units		17,000	units
Estimated sales price	$	15.00		$	26.00
Estimated manufacturing cost per unit
Direct materials	$	9.50		$	11.50
Direct labor		2.50			5.00

Fixed manufacturing overhead		3.00			3.00
