Answer:
$62,490.65
Step-by-step explanation:
If we assume her deposits are at the beginning of the month, and that the interest is compounded monthly, the future value is that of an "annuity due." The formula is ...
FV = P(1+r/n)((1+r/n)^(nt)-1)/(r/n)
where r is the APR (.0276), n is the number of yearly compoundings (12), P is the monthly payment ($280), and t is the number of years (15). Putting the numbers into the formula and doing the arithmetic, we get ...
FV = $280(1.0023)(1.0023^180 -1)/(.0023) ≈ $62,490.65
Angelica's account balance after 15 years will be $62,490.65.
_____
If her deposits are at the end of the month, the balance will be $62,347.25.

There are no such numbers in real numbers.
Do you perhaps want a solution in complex numbers?
4x + 5 = 25
-5 -5
4x = 20 (divide 4 from each side)
x = 5
Answer:
m = 
Step-by-step explanation:
Given
y = mx + b ( isolate the term in m by subtracting b from both sides )
y - b = mx ( divide both sides by x )
= m
Let's look over the meaning of each option:
Theocracy: Theo- means that it is relating to religion. For example, Theology is the study of religion. This is a system where religious leaders control the country, but it is NOT an economic system.
Monarchy: Monarchy is when there is a king, queen, emperor, etc. It is not an economic system either.
Fundamentalism: A political system that strictly abides by a set of fundamentals. Someone who wants a constitution to be the highest form of law is a fundamentalist. However, this is also not an economic system.
Socialism: WINNER WINNER CHICKEN DINNER! Socialism is a system similar to communism where the government controls the economy and there is communal ownership. This is also the only option which is both a political and economic system.
TL;DR: The answer is Socialism.
