A condensed income statement for the Commercial Division of Maxell Manufacturing Inc. for the year ended December 31 is as follows:

Sales $3,900,000.00

Cost of goods sold 2,410,000.00

Gross profit $1,490,000.00

Operating expenses 1,100,000.00

Income from operations $390,000.00

Invested assets $3,250,000.00

Assume that the Commercial Division received no charges from service departments. The president of Maxell Manufacturing has indicated that the divisions return on a $3,250,000 investment must be increased to at least 16.00% by the end of the next year if operations are to continue. The division manager is considering the following three proposals:

Proposal 1: Transfer equipment with a book value of $321,500 to other divisions at no gain or loss and lease similar equipment. The annual lease payments would exceed the amount of depreciation expense on the old equipment by $110,000. This increase in expense would be included as part of the cost of goods sold. Sales would remain unchanged.

Proposal 2: Purchase new and more efficient machining equipment and thereby reduce the cost of goods sold by $515,000 after considering the effects of depreciation expense on the new equipment. Sales would remain unchanged, and the old equipment, which has no remaining book value, would be scrapped at no gain or loss. The new equipment would increase invested assets by an additional $1,820,000 for the year.

Proposal 3: Reduce invested assets by discontinuing a product line. This action would eliminate sales of $588,000, reduce cost of goods sold by $413,700, and reduce operating expenses by $176,000. Assets of $1,398,000 would be transferred to other divisions at no gain or loss.

If the Commercial Division were in an industry where the profit margin could not be increased, how much would the investment turnover from the past year, as calculated in part 1 (1.2) have to increase to meet the presidents required 16.00% return on investment? Enter your increase in investment turnover answer as a percentage of current investment turnover. (Note: If required, round your intermediate and final answer to two decimal places.)
