Answer:
a. How long will the current bridge system work before a new bracing system is required?: 64.18 years or 64 years and 2 months.
b. What if the annual traffic rate increases at 8 % annually: The bracing system will last for 24.65 years or 24 years and 7 months.
c. At what traffic increase rate will the current system last only 12 years: 17.13%
Explanation:
a. Denote x is the time taken for the number of pedestrian to grow from 300 to 2000. The current pedestrian is 300, the grow rate per year is 3% or 1.03 times a year. Thus, to reach 2,000, we have the equation: 300 x 1.03^x = 2000. Show the equate, we have 1.03^x = 6.67 <=> x = 64.18
b. Denote x is the time taken for the number of pedestrian to grow from 300 to 2000. The current pedestrian is 300, the grow rate per year is 8% or 1.08 times a year. Thus, to reach 2,000, we have the equation: 300 x 1.08^x = 2000. Show the equate, we have 1.08^x = 6.67 <=> x = 24.65.
c. Denote x as traffic increase rate. The current pedestrian is 300, the grow rate per year is (1+x) times a year. Thus, to reach 2,000 after 12 years and thus a new bracing system to be in place, we have the equation: 300 x (1+x)^12 = 2000. Show the equate, we have (1+x)^12 = 6.67 <=> 1+x = 1.1713 <=> x = 17.13%.
Switzer Inc. should give the value of the computers at what they are currently worth to replace. After the two years, they now cost $400 to replace them so the value Switzer Inc. should place on their year end report is $400 due to that being the cost to replace in current day.
Answer:
b.$7,172.16 favorable
Explanation:
std rate $ 13.13
actual rate $ 12.20
actual hours 7,712
difference between actual and standart rate $0.93
As it is positive the variance is favorable as we spend less per hour than standard.
Now, we multiply by the actual hours to get the rate variance:
7,712 hours x $0.93 = $7,172.16
Equilibrium is the intersect of the two curves. The curves show you how much the producers supply and how much the consumers demand at each possible price.
The demand curves shows that the higher the price is, the less the consumers demand. That's obvious—the consumer wants something, but not at any price. He's only willing to pay so much. If the price goes higher and higher, less and less people want to buy the good.
The higher the price is, the more the producers can supply. This is because some producers are able to produce at lower costs; they're better and more efficient than other producers. Other producers, who produce at higher costs, would go bankrupt if they tried to produce at lower prices. But when the price goes up, even the worse producers, who have higher costs, are able to make profit. So, more producers supply to the market.
What happens now, when the price gets lower than the equlibrium? As you can see from the chart, producers would supply less than consumers would be willing to consume at that particular price. There would be SHORTAGE. This happens when the goverment sets price ceilings (like on gas in the 30's). An opposite situation happens when there is price floor—for example minimum wage (because wages are prices too; prices of labor). In that case, there is surplus—in case of minimum wage that means surplus of labor (unemployment).
But when the markets are free to set the price, they will quickly establish equlibrium again. The producers will see that there is a shortage. They'll realize they can set higher prices and make bigger profits. They can't set higher price than the equilibrium though, because there would be surplus and they would have their warehouses stuffed with goods noone wants to buy at that price.
This is the Answer Am 100% sure.
<span>When mp3 players emerged and cassette players declined in popularity, the type/s of unemployment created were of those who are making the wires, the mp3 players, the cassette players, the CD players and even the owner or companies who are suppliers of products that are needed to assemble the machines.</span>
