Markups; cost-plus pricing--The following is Drago's Company's income statement for the past year.

Sales revenue	$ 300,000.00
Cost of goods sold	$ 120,000.00
Gross margin	$ 180,000.00
Operating expenses	$ 130,000.00
Operating income	$ 50,000.00

Could use some help with the following four points:

A: What is the markup percentage on Cost of goods sold?

B: What is the markup percentage on total costs?

C: What is the gross margin percentage?

D: If the company wanted to sell a new product that costs $45 wholesale while keeping the same markup structure, what will be the price of the new product?
