Use the compound interest formula to solve this question.
The formula is
A=p (1+r/k)^kt
A future value 3000
P amount deposited?
R interest rate 0.04
K compounded 4 times
T time 5years
Solve the formula for p
P=A÷(1+r/k)^kt
P=3,000÷(1+0.04÷4)^(4×5)
p=2,458.63
Is the question - did they mistakenly say "dollar" rather than "years?"
x = # of years
10,000 = 20,000 (0.85)^x, first divide both sides by 20,000
0.5 = (0.85)^x, next take the ln of both sides
ln 0.5 = ln (0.85)^x, by rules of logarithms you may move x to make it a coefficient of the logarithm
ln 0.5 = x (ln 0.85), divide both sides by ln (0.85)
x = (ln 0.5)/ (ln 0.85) = (-0.693)/(-0.1625) = 4.26 years
You solve the equation for x. First, subtract 7 from both sides.Then subtract 3x from both sides. Then you should get 2x = 16. Divide both sides by two, and you will get x=8.
