What system of equations would you use to solve the problem below? A test is worth 100 points. Multiple-choice questions are worth 3 points and
short-answer questions are worth 5 points. If the test has 28 questions, how
many multiple-choice questions are there?
A. m + s = 8
3m + 5s = 128
B. m + s = 100
3m + 5s = 28
C. m + s = 28
3m + 5s = 100
D. m. $ = 28
3m. 5s = 100

Step-by-step explanation:

here's the solution,

let number of multiple Choice questions be m

and number of short answer questions be s

1. total number of questions = m + s = 28

( total multiple choice questions + total short answer questions )

2. total points = total points of multiple Choice questions + total points of short answer questions

=》3m + 5s = 100

so, the required equations are :

=》m + s = 28

=》3m + 5s = 100

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%
