Listed price = $1.4 million
Down payment = 20% of $1.4 million = 0.2 x 1,400,000 = 280,000
Amount left to pay = $1.4 million - 280,000 = $1,120,000
Present value of an annuity is given by PV = P(1 - (1 + r/t)^-nt) / r
where: PV = $1,120,000
r = 5% = 0.05
t = 12
n = 30 years.
1,120,000 = P(1 - (1 + 0.05/12)^-(12 x 30)) / 0.05
1,120,000 x 0.05 = P(1 - (1 + 1/240)^-360)
56,000 = P(1 - 0.2238)
P = 56,000 / 0.7761 = 72,148.83
Therefore, the monthly payment is $72,148.83
The coefficients are the numbers next to the variable.
11r :- The coefficient is 11
7s :- The coefficient is 7
Let's call them: W and L
Then area: A = W × L
We can replace: L = 2 × W
So: A = W × 2W=98→
2W^2=98 →W^2=98/2=49
→W=√49=7
→L=2×W=2×7=14
Conclusion: The rectangle is 7*14 ft
Hope this helps :)
