Given:
Price of gold in 2001 = (0.5x+300)
Its price tripled in 2008 and then doubled in 2011. In 2016, its price dropped to 
of the price in 2011.
To find:
An expression for the price of gold per ounce in 2016.
Solution:
We have,
Price of gold in 2001 
Its price tripled in 2008.
Price of gold in 2008 
Then doubled in 2011.
Price of gold in 2011 
In 2016, its price dropped to of the price in 2011.
Price of gold in 2016 
Therefore, the required expression for the price of gold per ounce is (2x+1200).
If Lamont withdraws $2,750 monthly, he will be <u>66 years old</u> (after 134.326 months) when the money runs out.
<h3>How is the number of monthly withdrawals calculated?</h3>
We can calculate the number of monthly withdrawals using an online finance calculator.
It determines the number of periods it will take for the investment to be exhausted, given an interest rate of 3.8%.
I/Y (Interest per year) = 3.8%
PV (Present Value) = $300,500
PMT (Periodic Payment) = $-2750
FV (Future Value) = $0
<u>Results</u>:
N = 134.326 months
Years = 11 years (134.326/12)
Age at FV = $0 is 66 years (55 + 11)
Sum of all periodic payments = $-369,397.09 (134.326 x $-2,750)
Total Interest = $68,897.09
Thus, making a monthly withdrawal of $2,750 will exhaust the investment when Lamont turns <u>66</u>.

The equation you'd make would be (2x-2)+(2x-2)+x+x=20 because the length is 2 m less than the width (x). To simplify, it'd be 6x-4=20 because you combine like terms. You then move the -4 over to the 20 to make it 6x=24. The final answer is 4 meters.
