Please assist me in finding the correct solution.

Eli Lilly is very excited because sales for his nursery and plant company are expected to double from $650,000 to $1,300,000 next year. Eli notes that net assets (Assets Liabilities) will remain at 50 percent of sales. His firm will enjoy an 12 percent return on total sales. He will start the year with $250,000 in the bank and is bragging about the Jaguar and luxury townhouse he will buy.

a. Compute his likely cash balance or deficit for the end of the year. Start with beginning cash and subtract the asset buildup (equal to 50 percent of the sales increase) and add in profit. (Negative amount should be indicated by a minus sign.)

b. Does his optimistic outlook for his cash position appear to be correct?
