The answer is probably a key word in the lesson material that you are forgetting, and since I have not read your lesson material I can't be sure what the wording is. But all those things have to do with advertising, so best guess is Market exposure or something like that. If that jogs your memory about a key phrase that you learned in the lesson material then go with that though. Goodluck!
<span>1 candy cost 1
2 candies cost 1+.50=1.50 ( here D is not an integer, hence we cannot buy 2 candies . so we can reject all cases where D is non Integer)
3 candies cost 1.50 +1 =2.50
4 candies cost 2.50+.50= 3
5 candies cost 3+1= 4
6 candies cost 4+.50= 4.50
7 candies cost 4.50+1=5.50
8 candies cost 5.50.+.50= 6
9 candies cost 6+1= 7
.....
13 candies cost =10
(i) D is prime
D=3 and N=4 (N is even)
D=7 N=9 (N is odd )
not sufficient
(ii) D is not Divisible by 3
D=1 N=1
D=4 N =5
D=7 N=9
D=10 N=13
so we see if D is not divisible 3 then N is always odd.</span>
Answer:
The correct answer is option a and c.
Explanation:
The fed cannot control the money supply up to a great extent in the real world. This is because the feds can control the amount of required reserves that a commercial bank holds. But they cannot control the amount of excess reserves that a bank decides to hold which affects the money supply.
At the same time, the feds cannot control the amount of money that the households decide to hold as currency which also affects the money supply.
The amount of excess reserves a bank decides to hold affects the deposit-reserve ratio. While the amount of money that households decide to hold affects the currency deposit ratio. Both of these ratios affect the money supply.
