Gavin Mills has an existing facility that it paid $30,000,000$ for $10$ years ago. It has $3$ choices for this facility now: sell it outright for $9\mathrm{.}5$M today, lease it for the next $4$ years to a supplier, then sell it at the end of the last year of the lease for $5$M$,$ or use it to produce flax seed for $4$ years, then sell it at the end of the last year of production for $6$M$,$ but it will have to be upgraded $($today$)$ for use at a cost of $1\mathrm{.}5$M $($not paid under the lease option$).$ If it is used by Gavin to produce flax seed it can be sold for $$42$ a bushel with a contribution margin ratio $($how much the firm keeps after variable costs of production$)$ of $25\%.$ To operate the plant, Gavin will incur $$200,000$ per year of fixed costs, regardless of production levels $($not applicable to the lease$).$ Gavin forecasts that it will sell the following bushels in each of the next $4$ years: $200,000,300,000,400,000,100,000.$ The lease terms would be $$2$M per year plus a $$200,000$ per year reduction in costs for the supplies Gavin buys from the leasee. Please use a WACC of $12\%.$

What would the CMR have to increase to in order to change the decision? Please consider whole number changes in percent $($i$.$e$.30\%$ to $31\%)$ and enter your response in whole numbers with no units $($i$.$e$.\%)$ and NO decimal places: $"21\mathrm{.}6\%"$ would be $"21".$
