Answer:
a) Gold = $1,380; Silver = $1,020
b) Gold = $1,300; Silver = $980
Explanation:
a) At first, with Qg = 60 and Qs = 270, the equilibrium prices for gold and silver are found by solving the following linear system:

Equilibrium price of gold is $1,380 and the price of silver is $1,020.
b) If the supply of gold increases to 120, since the goods are substitutes, there will be an increase in overall supply and the equilibrium price of gold and silver will decrease as follows:

Equilibrium price of gold is $1,300 and the price of silver is $980.
  
        
             
        
        
        
It is true that because of the substitution problem, the CPI tends to overstate the true change in the price of the typical basket of consumer goods.
<h3>What is CPI?</h3>
- A consumer price index measures a market basket of goods and services that households have purchased at a weighted average price. 
- The measured CPI fluctuates to reflect changes in prices over time.
- One of the most popular methods for determining inflation and deflation is the CPI.
-  An essential gauge of an economy's health is inflation. The CPI and other indexes are used by governments and central banks when making economic decisions. 
- The decision to raise or cut interest rates is crucial among these.
- If the CPI increases, it indicates that the average rate of change in price over time has increased. The cost of living and income are eventually changed as a result of this.

In simple interest, the interest rate is
i=(10500-9000)/9000=16.67%
In compound interest, compounded monthly,
10500=9000(1+i/12)^12
=>
APR=12(10500/9000)^(1/12)-1
=11.155%
(effective interest is still 16.67%)
