how much interest did she earn? well, simply subtract how much came out of her pocket, from the accumulated amount, whatever is left, is the interest
how much did she put out of pocket? well, out of her pocket came 1200 every year for 12 years, or 1200 * 12
Answer:
Step-by-step explanation:
The formula you need for this is
where
A(t) is the amount after a certain number of years has gone by,
P is the initial deposit,
r is the interest rate in decimal form,
n is the number of compoundings done per year, and
t is the amount of time in years.
For us,
A(t) = 11900
P is 250
r is .048
n is 12 (there are 12 months in a year)
t is our unknown. Filling in:
which simplifies a bit to
. Now we'll divide both sides by 250:
and then take the natural log of both sides to bring that t down out front:
and then
ln(47.6) = 12t ln(1.004). Now divide both sides by ln(1.004) to isolate the 12t:
967.6383216 = 12t and divide both sides by `12 to get
t = 80.6 months which is 6.7 years
Answer: A
Step-by-step explanation: common sense
Answer:
Angle A = 32
Angle B = 96
Angle C = 52
Step-by-step explanation:
180 - 52 = 128
128 / 4 = 32
Angle A = 32
Angle B = 3 x 32 = 96
Angle C = 52
Check:
32 + (3 x 32) + 52 = 180
