In april 2011, consolidated edison (ed) stock cost $50 per share and yielded 5% per year in dividends, while national grid (ngg) stock cost $50 per share and yielded 6% per year in dividends.† if you invested a total of $52,500 in these stocks and earned $2,815 in dividends in a year, how many shares of each stock did you purchase?

Total amount Invested = 52,500

Since both stocks cost 50, total number of share he purchased = 52,500/50 = 1,050 shares

Total number of shares = 1,050

Let x be the total number of Ed shares.  Therefore Ngg shares = 1050-x

Ed Stock dividend return = x*0.05*50

Ngg stock dividend return = (1050-x)*0.06*50

Since total was  2,815, we add and equate the two as shown below:

x*0.05*50 + (1050-x)*0.06*50 = 2815

2.5x + 3150 -3x = 2815

0.5x = 335

x 335/0.5

x = 670 shares

Ed stock = 670 shares

Ngg stock =1050-670 = 380 shares

So, you purchased 670 shares of consolidated edison (ed) stock and 380 shares of national grid (ngg) stock

1   all nations face the problem of scarcity because there are limited resources and unlimited wants. nations do not have enough factors of production to produce everything that their population wants. entrepreneurial resources initiate businesses to make new goods and services; labor resources produce goods and services.

2 there are four factors of production: natural resources, labor resources, capital resources, and entrepreneurial resources. natural resources are raw materials from nature that are used to produce goods. trees, water, and grains are natural resources. some natural resources, such as wheat and cattle, are renewable
