Tessa has nine children and hires two babysitters at a time. Tim charges $15 per hour with the first hour free,
and Yu charges $10 per hour plus a flat fee of $20.
Write an expression for Tessa's total cost, and say what
the variable represents. If they both work 8 hours,
what's Tessa's total cost?

answer: the answer is 127 degrees

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

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%
