Por un sistema de ecuaciones, tiene-se que:
- Cada lapiz cuesta 20 ptas.
- Cada boligrafo cuesta 50 ptas.
-------------------------
- Considera-se un sistema de ecuaciones, con cada boligrafo custando x y cada lapiz custando y.
- <u>Boligrafo cuesta 30 mas que un lapiz</u>, o sea,

- <u>8 boligrafos y 15 lapices cuesta 700</u>, o sea,

-------------------------
- Aplicando el <u>primer ecuación en la segunda, </u>tiene-se el cuesto de cada lapiz:






Cada lapiz cuesta 20 ptas.
-------------------------
Por fin, el cuesto de cada boligrafo es dado por:

Cada boligrafo cuesta 50 ptas.

Answer: D. $3,450
Given: 2,500 shares of a stock bought for $8 a share
<span>Probabilities: the stock will rise to a value of $32 a share is 22%</span> <span> the stock will fall to $3 a share is 78%</span>
<span>Question: What is the expected value of the investor’s profit from buying the stock?</span>
Solution: (22%(32-8)-78%(8-3))2500
(.22(24)-.78(5))2500
(5.28-3.9)2500
(1.38)2500
3450
