Investing General Electric Co. stock sells for $29 a share and has a 3-year average annual return of $2 a share. The beta value is 1.10.Procter & Gamble Co. sells for $86 a share and has a 3-year averageannual return of $4 a share. The beta value is .53. Tori wants to spend no more than $12,000 investing in these two stocks, but she wants to earn at least $700 in annual revenue. Tori also wants to minimize therisk. Determine the number of shares of each stock that Tori shouldbuy. (Data from: www.morningstar.com.)

This information is needed to solve #7 - 12. After picking cotton from the farm, it is
stored in rectangular "modules" which are later transported to a cotton gin for
processing. The average module carries 21 tons of raw cotton, out of which only
(30+ E)% is useful "lint" that can be used to make clothing and textiles. In 2017,
the USDA estimated that 2.1×107 bales of lint (each weighing 500 lbs.) were
produced in the country. Your region produced (B x C) bales, with an average yield
of (1000 - A) lbs./acre. There are (100+ A) gins in your region. The market price
of lint is 78 ¢/lb.
