Answer:
A = Pert is formula for continuously compounded interest
A = final amount = 2000
P = principal = 1000
e = euler's number (on calculator)
r = interest rate as decimal = .075
t = time in years
Your mistake is that 7.5% as a decimal is 7.5/100 = .075
not 7.5
2000 = 1000e.075t
e.075t = 2000/1000
e.075t = 2
take natural log of both sides
ln e.075t = ln 2
.075t = ln 2
t = ln2/.075
t = 9.24 years
Answer:
C) The expressions are not equivalent because Ella would get different results when substituting different numbers for f.

Let event A be the first light being red.
Let event B be the second light being red.
P(A) = 0.48
P(A & B) = P(A) * P(B) = 0.35
P(B) = 0.35 / P(A)
P(B) = 0.35 / 0.48
P(B) = 0.73
Since the lights are independent, P(B|A) = P(B) therefore d is the correct answer.
