The Atlantic Ocean has an average depth of about 12,000 feet, to the nearest thousands. It is the second largest ocean in the world. The Atlantic Ocean and the Arctic Ocean are separated by a submarine ridge that extends from the south east of Greenland to the North Scotland. The atlantic Ocean can be divided into two parts based on its shape and they are North Atlantic Ocean and South Atlantic Ocean. These two parts have totally different type of water currents. The North Atlantic Ocean has some of the busiest shipping lanes as commercial ships ply through this route.
Using proportions, it is found that $55.7 billion was donated to educational organizations.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Of the $371 billion donated in total, 15% went to educational organizations, hence the amount is given by:
A = 0.15 x 371 = $55.7 billion.
Hence $55.7 billion was donated to educational organizations.

9x - y = 15
2x + 8y = 28
Use the substitution method.
Solve for y in the first equation.
9x - y = 15
-y = 15 - 9x
y = -15 + 9x
Now plug in y into the second equation.
2x + 8(-15 + 9x) = 28
2x - 120 + 72x = 28
74x - 120 = 28
74x = 148
x = 2
Plug x back into the rewritten first equation.
y = -15 + 9(2)
y = -15 + 18
y = 3
x = 2, y = 3
