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.
We have been given net of a pyramid. We are asked to find the total surface area of the pyramid.
The surface area of the pyramid will be area of base plus area of 4 triangular sides.
We have been given that base of pyramid is square, so area of base will be square of base side.
Let us find area of one triangular side.
Now we will multiply area of one triangular face by 4 to find area of 4 triangular faces.
Total surface area of pyramid would be area of base plus area of 4 triangular faces.
Therefore, 220 square inches of copper sheet are needed to make one pyramid.
