Security a Is Estimated to Be Linearly Related to Four

Security A is estimated to be linearly related to four risk factors: F₁,F₂,F₃,and F₄ such that its required rate of return can be expressed as ER_(A) = m_o + n₁F₁ + n₂F₂ + n₃F₃ + n₄F₄,where m_o is the risk-free rate.If the risk-free rate is 5.5 %,what is the required rate of return of Security A,where n₁,n₂,n₃,and n₄ are 0.3,0.6,0.9,and 0.12,respectively,and F₁,F₂,F₃,and F₄ are 6 %,7 %,10 %,and 8 %,respectively?
