Ok in 2001 the Barnes had 45,000, and 12% was dedicated to savings.
in 2002 their income went up by 10%, 10% of what? well, 10% of 45000, how much is that? well, 10% of anything is just (10/100) * anything
so 10% of 45000 is (10/100) * 45000 or just 4500, you simply chop off a zero
so, it went from 45000 to 45000 + 4500 or 49500
now, they do their budget the same, savings is 12% in 2002, just like in 2001, alrite, how much is 12% of 49500? well, 12% of anything is just (12/100) * anything
so... I'm sure you'd know how much (12/100) * 49500 is
Answer:
The answer is "40 nickels/standard coins"
Step-by-step explanation:
The ratio of 40 nickels/standard coins is constant, that is 1 roll with coins per 40 nickels, that's why the equation is y = 40 
We have that
(14/3)=(x/y²)-----------> 14*y²=3*x
then
(14/x)=(3/y²)
the answer is
3/y²
