18 * 7.95 = $143.10

238.50 - 143.10 = 95.40

95.40/7.95 = 12

12 hours

Step-by-step explanation:

7.95h + 7.95(18) = 238.50

7.95h + 143.10 = 238.50

7.95h = 238.50 - 143.10

7.95h = 95.40

h = 95.40 / 7.95

h = 12 < he would need to work 12 hrs as a host

step-by-step explanation:

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%
