The expression 1.08s + 1.02b1.08s+1.02b predicts the end-of-year value of a financial portfolio where ss is the value of stocks and bb is the value of bonds in the portfolio at the beginning of the year. what is the predicted end-of-year value of a portfolio that begins the year with \$200$200 in stocks and \$100$100 in bonds?

The predicted end-of-year value is $318.

Step-by-step explanation:

We are given the expression for the end-of-year value of the financial portfolio as,

, where s = value of the stocks and b = value of the bonds.

it is required to find the end-of-year value of a portfolio when,

value of the stocks, s = $200

value of the bonds, b = $100

So, substituting the values in the given expression, we get,

→ → → y= 318

Thus, the predicted end-of-year value is $318.

step-by-step explanation:

your welcome : )

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
