Use the Markdown Pricing Decisions spreadhseet model and a two-way data table to find the total revenue if days at full retail vary from 15 to 35 in increments of 5 and the itnermediate markdown varies from 25% to 60% in increments of 5%.

I'm having trouble getting the answers for this two way variable data table. It keeps giving me the same answers.
