Answer:
Rising home prices in recent years means that more people will need to take out mortgages.
Explanation:
We can see in the graph that there is an upward trend; that is, the average price of homes in the US is rising. While there was a slight decrease from 2010 to 2012, overall the average is still increasing.
Since the prices are increasing, more people will need to take out mortgages, as it will e harder to have the cash saved up to purchase the home.
The formula for compound interest is:
A=P(1+r/n)^(nt)
Where A represents the amount of money in the account after t years, P is the principal (investment), n is the number of compoundings per year, and r is the interest rate in decimal form.
P=11,100
r=.031
n=12 (monthly)
t=19
A=11,100(1+.031/12)^(12*19)
A=11,100(1+. 002583)^(228)
A=11,100(1.002583)^(228)
A=11,100(1.80082)
A=$19,989.10
