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).

Answer:
C. It is just right.
Step-by-step explanation:
We want to compare the ratios ...
bags : liters = 15 : 2
and
bags : liters = 90 : 12
If we multiply the numbers of the first ratio by 6, we see they are identical to those in the second ratio:
(15)(6) : (2)(6) = 90 : 12
The ratio of bags to liters for Peggy's tea matches the ratio Kermit likes. He will think it is just right.
IF 12 copies cost $0.66 you have to divide 0.66/12 and you will get the cost for 1 copy: 0.66/12= $0.055 per each copy.
If Melyssa needs 56 copies, you have to multiply 0.055*56= $3.08
