The answer directly above is wrong, but the initial set-up is right.  235 is the answer.

Write them as a ratio of integers (cents) first:\n1250 / 875\n\nRemove a common factor of 5 from top and bottom:\n250 / 175\n\nRepeat for another 5:\n50 / 35\n\nOops, we can do it again:\n10 / 7\n\n(Note: this is equivalent to 1.428571... in decimal, so the previous answer was right about this, but the problem asked to do it as a ratio of whole numbers.)\n\nSo the ratio of the prices is 10 / 7.

First off, stop trading penny stocks, you will almost certainly lose money, particularly if you don't understand some basics like how the spread works.  To answer your question 0.0001 is one hundredth of a penny.  You need one hundred of them to make one cent.\n\nSecondly, you should probably not even attempt day trading at this point.  You need to have a much better understanding of how this all works.  Take some time, take a course, read some books, learn from some other traders, but whatever you do, don't try and trade penny stocks!!

His profit will actually be found by taking his price minus all of his expenses - you can't just take the derivtive of the price function.  Since the price function given is per widget, multiply it by x to find the total revenue from the selling of x widgets.  The costs given are already given in terms of a total number of widgets, so we can just add those up.  So you're really looking at a profit function\n\nP(x) = x[90 - (x/24)] - (1200 + 60x + x^2/24)\n= 90x - (x^2/24) - 1200 - 60x - x^2/24\n= - 1200 + 30x - x^2/12\n\nTaking this derivative you get\nP'(x) = 30 - x/6\n\nTo find the max profit, set this to 0 and solve for x:\n0 = 30 - x/6\n30 = x/6\nx = 180\n\nSo after selling 180 widgets, you'll maximize profits.  And putting this back into the original per unit price function, you find that you're selling them at\n\nPrice = 90 - x/24\n= 90 - 180/24\n= $82.50 each

You must divide the amount of the profit by the wholesale price.  Trivially, the profit is $0.60.  $0.60 / $0.05 = 12.  To get a percent, you must mulitply this result by 100%, giving you 1200% profit.  Not bad!

Use the $1,500 to invest in something, i.e. lawn mowers, snow blowers, etc., that you can turn around and use to make even more money.

yes, I think you can, many try to raise their prices so much to make a buck, that they price themselves right out of business.  You have to make a profit but you need to be realistic about making a buck. If people like your product and you are an honest person and keep your prices fair and still make a profit  you can and will make it work.

I'm not aware of any limits.  You can buy or sell as many as you want.  In some developed markets if you buy more than approx 30% of the stock you can be forced to make an offer for the remaining 70%.

For a major label, it's about less than a dollar, because they make the actual CD in thousands so they get a discount. And the note he made about small number of musicians make money off their music is true in a concept. Commonly now a days, if you sell 500,000 albums you'll make a profit, especially if you are rapper.
