Sales of a product, under relatively stable market conditions but in the absence of promotional activities such as advertising, tend to decline at a constant yearly rate. This rate of sales decline varies considerably from product to product, but seems to remain the same for any particular product. The sales decline can be expressed by the function defined by the next formula. S(t)=So e at In this formula S(t) is the rate of sales at time t measured in years, So is the rate of sales at time t= 0 and a is the sales decay constant. If a = 0.09 and So=90,000, find the number of years it will take for sales to fall to half the initial sales. It will take about years for sales to fall to half the initial sales. (Type an integer or decimal rounded to the nearest tenth as needed.)

Sales of a product, under relatively stable market conditions but in the absence of promotional activities such as advertising, tend to decline at a constant yearly rate. This rate of sales decline varies considerably from product to
product, but seems to remain the same for any particular product. The sales decline can be expressed by the function defined by the next formula.
S(t)=So eat
In this formula S(t) is the rate of sales at time t measured in years, So is the rate of sales at time t= 0 and a is the sales decay constant. If a = 0.09 and So=90,000, find the number of years it will take for sales to fall to half the
initial sales.
It will take about years for sales to fall to half the initial sales.

10.23. Question. An umbrella-shaped island has a population of 499 healthy people. Alice, who is injected with the T-virus, enters the island on day 0. It is known that anyone infected with the T-virus will become a zombie after 24 hours. Assume that the infected (zombies are considered infected) will spread the virus (through biting) and no one on this island can escape from it. The rate of virus transmission is proportional to the product of the number of infected and non-infected. Thus, if x(t) denotes the number of the infected on day t, then dx dt = kx(500 — x). On day 10, it is observed that 20 people are already infected. Answer the following questions. (a) How many zombies are on the island on day 16? (b) On day 20, how many people are infected but not yet turned into a zombie? (c) A rescue boat with 50 available seats is to be sent to the island. What is the earliest day the boat should be sent to ensure it can rescue all survivors (those not infected)?

For Shock G: Suppose the economy starts in the long run equilibrium. Illustrate changes that the shock will cause in the short run (using AD-SRAS). Explain why each curve shifts. Determine how the price level and output will be affected in the short run. Mark the output gap on the diagram. Is the output gap positive or negative? Is the economy is booming, or is it in a recession? On the same diagram illustrate how the economy will adjust to the shock in the long run and explain the mechanism. Determine how the price level and output will be affected in the long run. G. The government increases its spending on national defense As a result of this shock, in the short run the (SRAS Curve/AD Curve) will shift? In consequence, in the short run prices and output will?
