Consider the following information: Rate of Return if State Occurs State of Economy Probability of State of Economy Stock A Stock B Stock C Boom 0.30 0.23 0.31 0.30 Good 0.15 0.16 0.11 0.12 Poor 0.30 0.02 –0.08 –0.07 Bust 0.25 –0.22 –0.24 –0.13 a. Your portfolio is invested 25 percent each in A and C and 50 percent in B. What is the expected return of the portfolio

was my answer wrong?

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
