English

Damm [24]3 years ago

The theory of plate tectonics states that the Earth's surface, the upper mantle and crust, was once made up of enormous rock plates that broke into smaller pieces approximately 300 million years ago. These smaller, broken plates form a more fluid rock surface in the mantle. Over time, the plates move and morph into natural land boundaries. This explains natural land phenomena, such as earthquakes and tsunamis.So A

You seek to make a 40% return on a $1,500 investment. Apple stock yields a 30% return, while Microsoft stock yields an 80% retur
andriy [413]

Answer:

80% of Apple shares and 20% of Microsoft shares must be acquired.

Explanation:

To determine in what proportion each stock can be purchased, it must be determined how much profit will be obtained according to the percentage in which each stock is subscribed. Thus, acquiring 60% of Apple stocks and 40% of Microsoft, the benefit will be as follows:

((60 x 30) + (40 x 80)) / 100 = X

(1800 + 3200) / 100 = X

5000/100 = X

50 = X

Therefore, the ratio must be greater than 60/40. So, testing an 80/20, the benefit will be as follows:

((80 x 30) + (20 x 80)) / 100 = X

(2400 + 1600) / 100 = X

4000/100 = X

40 = X

Therefore, 80% of Apple shares and 20% of Microsoft shares must be acquired.
