Given:
Selling price = 6.99
Cost = 4
The dollar markup is computed by deducting the cost from the selling price.
6.99 - 4 = 2.99 is the dollar mark-up based on cost.
2.99/4 = 0.7475 x 100% = 74.75% is the percentage mark-up based on cost.
Answer:
Cindy has more amount than Jimmy.
Explanation:
Amount invested by Cindy P = $3000
Annual rate of interest = 8%
As the amount is compounded semiannually
So rate of interest
%
Time = 20 year
So time period n = 20×2 = 40
So amount own by Cindy 
$
Amount deposit by jimmy P = $3000
Annual rate of interest = 7.75 %
As the amount is compounded monthly
So rate of interest
%
Time period = 20×12 = 240
So amount own by Jimmy 
$
From the calculation we can see that Cindy has more amount than Jimmy.

I would say that all of the following are steps to help you be a good problem solver except B and C. You need to define the problem and then set about creating solutions. For example, if it is becoming too expensive to haul ore out of an open pit because it its too deep so the haulage costs are prohibitive, then a potential solution involves decreasing haulage costs by shortening the haul which can be resolved by extending in pit conveyors and crusher down close to the ore deep within the pit.
