Ans. the rate of return of this invesment is 3.5278% annual.
Explanation:
Hi, what we need to do here is to find the future value of all six payments, beginning when the child turns 12, which will end when he turns 17. One year later (when the child turns 18) he will receive $25,000 per year, for the next 4 years. This is the equation that we need to use (and solve for "r").

Where:
A1=$14,000
A2=$25,000
So, everything should look like this

As you can see, this would take forever to solve, so what we have to do is to use MS Excel, we have to use the "Goal Seek" function. Please check the MS Excel spread sheet attached to this answer.
Please use this function with the following parameters.
Set Cell: G7
To Value: 0
By changing cell: G2
Ans. 3.5278%
Best of luck.
To solve for the cross-price elasticity of demand:
Take the quantity of the diamonds demanded and divide it by the decrease in the price of sapphires.
Cross-price elasticity of demand = 15/25
Cross-price elasticity of demand = 0.6
When you are solving for the cross-price elasticity of demand, you are seeing the response to the demand of a item when price changes for another good.
It should be realistic and evaluated frequently
Answer:
b) $10 trillion
Explanation:
Price level = NGDP / RGDP = 2
NGDP / RGDP = 2
As per the quantity theory of money,
MV = PQ
M.(2) = 20
M = 10 trillion
Therefore, The money supply is $10 trillion.
