1.Discuss the theories that consider idiosyncratic risk positive return

2.the profit made by a company when 60 units of its product is sold is r 1 600.00. when 150 units of its products are sold, the profit increases to r 5 200.00. assuming that the profit function is linear and of the form p(u) = a +bu where p is the profit in rands and u is the number of units sold, determine the values of a and b.

3.You are running a project to build fences around a square lot, with one side scheduled per week.Each of the sides will have a fence with an estimated labor cost of $1000, so the total project labor budget (BAC) is $4000.

At the end of week 2, Planned Value (PV) is $2000.Also, at the end of week 2, a total of $3000 in labor has been spent (Actual Cost, AC).The fence on one side of the lot is completed and a partial fence has been constructed on a second side.

What would be the effect of including $2000 in materials in the project EVM analysis if they were all delivered and paid for at the beginning?

Derive formula for the calculation of working capital

5.Differentiate profit margin and net profit margin

6.I am writing a formula to help me calculate coupon deals for my shopping trip. My store doubles coupons $.99 or under, so I need a formula that does the following: If the value in cell D2 is less than $1.00, multiply the value by 2 and spit it out in D3.

7.Find the annual interest rate. I=$54, P=$900, t=18 months

8.Find current balance for Jeff's savings account if he had a balance of $396.80, made three deposits of $15, withdrew $125, and earned $1.04 interest

9.The profit for a product can be described by the function p(x)=202x-5000-x^2 where x is the number of units produced and sold. To maximize profit, how many units must be produced and solid? What is the maximum possible profit?

10. how do I explain a negative percent for sales that is positive compared to negative sales the prior year? Last sales was a -$1,296.00 and this year sales is $356.00 but when doing this formula of =(this year - last year)/last year the result is a negative percent. How do I explain the formula is correct although the sales is an increase?
