Equipment needed at Valero Corporation refinery for the conversion of corn stock toethanol, a cleaner burning gasoline additive, will cost $175,000 and have net cashflows of $35,000 the first year, increasing by $10,000 per year over the life of 5 years.Develop a spreadsheet chart that plots AW vs interest rate to show where (what interestrate) the project switches from financially justified to unjustified. Use AW as the verticalaxis of the chart, and interest (i) as the horizontal axis of the chart. Use a range ofinterest rates spanning from 10% to 20%, and use increments of 1%. Label both axesand use a title for the chart.
