Wendy was awarded a volleyball scholarship to the university of michigan, so on graduation her parents gave her the dollar-sign 19,000 they had saved for her college tuition. she opted to invest some money in a privately held company that pays 10 % per year and evenly split the remaining money between a money market account yielding 2 % and a high-risk stock that yielded 40 %. at the end of the first year she had dollar-sign 22,440 total. how much did she invest in each of the three?

Total investment = $19000

Three investments

A. 10% per annum = $X

(Assumed simple interest, since compounding period not known)

B. low risk stock at 2% = (19000-X)/2

C. high risk stock at 40% = (19000-X)/2

Value at the end of one year

10%(X)+2%(19000-X)/2+40%(19000-X)/2 = 22440-19000

Simplify

0.1X+190-0.01X+3800-0.2X=22400-19000

0.11X=3990-3440

X=550/0.11=5000

So investments are $5000 on private company, (19000-5000)/2=7000 on low risk, and 7000 on high-risk.

b. a single paragraph.

a paragraph is a series of sentences that are organized and make sense, and are all related to a single topic . almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. this is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus the reader see the organization of the essay into subjects in order to be able to understand its main points.
