In the first round of a card game niki scored 20 points then she lost 10 points on one turn and an addiotal 25 points on her final turn

That's 35 points because one you take ten away from 20 you get 10 then you add 25 and that's how i got 35

3x + 4y -25 =0 represents the amount of change sianna should recieve

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
