Please help me answer the following question

Quantitative Problem: Lane Industries is considering three independent projects, each of which requires a $2.8 million investment. The estimated internal rate of return (IRR) and cost of capital for these projects are presented here Project H (high risk): Project M (medium risk): Cost of capital-1096 IRR-8% Project L (low risk) Note that the projects' costs of capital vary because the projects have different levels of risk. The company's optimal capital structure calls for 40% debt and 60% common equity, and it expects to have net income of $4,000,000. If Lane establishes its dividends from the residual dividend model, what will be its payout ratio? Round your answer to 2 decimal places. Cost of capital= 12% IRR= 14% Cost of capital = 6% IRR-7%
