An investment firm offers three types of equity investments,
a, b, and c. of the firm's clients, 30% invest in a, 50% invest
in b, and 20% invest in c. the rates of return are 10%, 6%,
and 7% for a, b, and c, respectively. what is the expected
value of the total return rate for the firm's clients?
6.2%
7.1%
7.4%
8.2%

The expected value of the total return rate for the firm's clients is C. 7.4%

Step-by-step explanation:

1. Let's review all the information given for solving the question:

Type of equity investments = A, B and C

Percentage of investment in each type of equity = 30% in A, 50% in B and 20% in C.

Rates of return of each type of equity investment = 10% for A, 6% for B and 7% for C.

2. Let's find the expected value of the total return rate for the investment firm:

Return rate for each type of investment = Percentage of investment * Rate of return

For A = 30% * 10% = 0.3 * 0.1  = 0.03

For B = 50% * 6% = 0.5 * 0.06 = 0.03

For C = 20% * 7% = 0.2 * 0.07 = 0.014

Total return rate = Return rate for A + Return rate for B + Return rate for C

Total return rate = 0.03 + 0.03 + 0.014 = 0.074

Total return rate = 0.074 * 100 = 7.4%

The expected value of the total return rate for the firm's clients is C. 7.4%

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
