Answer:
P>_5(10)^t
P<_1,000
Step-by-step explanation:
F(n+1)=-1/2f(n)
f(n)=-2f(n+1)
given f(1)=120
-2f(1+1)=120
f(2)=-60
f(2)=-2f(2+1)=-60
f(3)=30
f(3)=-2f(3+1)=30
f(4)=-15
f(4)=-2f(4+1)=-15
f(5)=15/2
F = final amount = unknown
P = 7000 is the principal (amount loaned)
i = 0.05 is the decimal form of 5% interest rate
t = 3 years go by
Plug those three values into the formula below and simplify
F = P*(1+i)^t
F = 7000*(1+0.05)^3
F = 7000*(1.05)^3
F = 7000*(1.157625)
F = 8103.375
F = 8103.38
<h3>Answer: Choice A) $8,103.38</h3>
