Answer:
A: $958.50
Step-by-step explanation:
Since we are solving how much money in total he will receive in one year, we know that annually means once a year. Therefore to solve this, we need to divide 6.5 by 100 since the way to turn a decimal into a percent is to multiply by 100, and we are trying to make it a decimal.
6.5 ÷ 100 = 0.065.
Next, we need to multiply 0.065 by 900. This is because we originally need to divide the denominator (900) from the numerator (X).
0.065 x 900 = 58.5 = $58.50
Now that we know 6.5% is equivalent to $58.50, we just need to add $900 and $58.50.
$900 + $58.50 = $958.50
The solution to your math problem is A: $958.50. Lan will have $958.50 by the end of one year.

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

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).
