Help! Can some one explain Jessica has her hair styled and wants to tip her hair stylist 18%. Write an equation that could be used to calculate the tip, y, for a bill of x dollars.

y = .18x

Step-by-step explanation:

The tip is going to be 18% of what she payed, and this says that x is what she payed. That means you can write it as:

tip = 18% of bill

y = 18% of x

18% of x an be written as .18x in decimal, so:

y = .18x

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

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%
