Answer:
-60% decrease
Step-by-step explanation:
60 is the old value and 24 is the new value.
percent change = x 100%
so for this problem, you can substitute the values given in the formula:
percent change = x 100% = x 100% =
-60% (decrease)
It's annuity problem
To solve your question use the formula of the present value of annuity ordinary which is
Pv=pmt [(1-(1+r)^(-n))÷r]
Pv present value?
PMT yearly payments 18000
R interest rate 0.09
N time 20 years
So
Pv=18,000×((1−(1+0.09)^(−20))÷(0.09))
pv=164,313.82
