Explanation:
A mark up is a percentage that is always applied on the cost to come up at a required gain over cost. The cost is always taken to be 100% when apply a mark up on cost.
If the mark up is of 27% and cost is 100% then a selling price of 22 will be equal to cost + markup.
Let cost be x.
Selling price = Cost + Mark up
22 = 100% * x + 27% * x
22 = 1x + 0.27x
22 = 1.27 x
22/1.27 = x
x = $17.3228 rounded off to $17.32
Answer:
A. Using a cap-and-trade system of tradable emission allowances will eliminate half of the sulfur dioxide pollution at a cost of $5,000 million per year.
B. If permits cannot be traded, then the cost of the pollution reduction will be $6,000 million per year
Explanation:
A. Using a cap-and-trade system of tradable emission allowances will eliminate half of the sulfur dioxide pollution at a cost of $5,000 million per year.
(250x20) =$5000
B. If permits cannot be traded, then the cost of the pollution reduction will be $6,000 million per year
[250(10)+350(10)]
=$2,500+$3,500
=$6,000
The last section in the stadium
t1 = 20min
the lowest-level
t2 = 5min
The average between those two sections of the stadium to find a seat is:
A = (t1 + t2) / (2)
A = ((20) + (5)) / (2)
A = (25) / (2)
A = 12.5min
Answer:
The average time to find a seat in these two sections at the stadium is
12.5min
