Step-by-step explanation:

2  Ms. Salgato doesn’t want to spend more than $375 that in symbols can be expressed as .

$100 is a constant so it doesn’t multiplies the x. The hour are instead a variable so $40 multiplies the x

so the final answer is

C  

9 no less than $455 can expressed as

if we solve the inequality

we have

so the final answer is A

13

$130 is a constant, while $3 mulplied a variable. No more means

we can now write and solve an inequality:

so the answer is C : 20

14

$9 multiplies a variable, a minimum can be expressed as

so the final answer is

B :

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%
