When does the government assume a contractionary fiscal policy position?
Step2247 [10]
The government assume a contractionary fiscal policy when the economy is strong. When the economy is strong, prices increases as a result of fierce competition for resources. In this situation, the government will assume a contractionary fiscal policy by reducing its spending and by increasing tax. This position will normally create a surplus for the government: a surplus is the amount of taxes left over after government spending.

A nonprofit group organizes its local fundraisers in teams, with each of its L team leaders responsible for D group directors, a
Akimi4 [234]

Answer:

Each of L team leaders has D group directors, making the total number of group directors equal to (L)(D). And each of those group directors has F fundraisers, again requiring multiplication: that total is (L)(D)(F). (You can try this by plugging in small numbers - if each of 2 leaders has 3 directors, you know there would be 6 directors)

So while statement 1 is not sufficient (there are multiple combinations that could get you to 81, such as L = 1, D = 2, and F = 39; or L = 1, D = 5, and F = 15), statement 2 guarantees that there is only one team leader. This is because 5 is a prime number, and you know that the number of group directors = LD. The only possible way for LD to equal 5 is if L is 1 and D is 5, or if D is 1 and L is 5. And since the stimulus tells you that there are more directors than leaders, the combination must be 5 directors and 1 leader. Accordingly, statement 2 is sufficient.
