Lavalier Company developed the following budgeted life-cycle income statement for two proposed products. Each product's life cycle is expected to be two years.

	Product AA	Product BB	Total
Sales	$400,000	$350,000	$750,000
Cost of goods sold	300,000	200,000	500,000
Gross profit	$100,000	$150,000	$250,000
Period expenses:
Research and development			(100,000)
Marketing			(75,000)
Life-cycle income			$75,000

A 12 percent return on sales is required for new products. Because the proposed products did not have a 12 percent return on sales, the products were going to be dropped. Relative to Product BB, Product AA requires more research and development costs but fewer resources to market the product. Sixty-five percent of the research and development costs are traceable to Product AA, and 40 percent of the marketing costs are traceable to Product AA. If research and development costs and marketing costs are traced to each product, life-cycle income for Product BB would be

a. $150,000.

b. $105,000.

c. $90,000.

d. $70,000.
