how much should a mother invest at the time her son is born in order to provide him with $50,000 at age 18? assume that the interest is 9% compounded monthly. the mother should invest $ (do not round until the final answer. then round to the nearest cent as needed.)
Answer
Explanation:
Step1: Identify variables
FV=$50000, r=0.09, n=12, t=18
Step2: Calculate nt
nt=12×18=216
Step3: Calculate monthly rate
r/n=0.09/12=0.0075
Step4: Compute compound factor
(1+0.0075)^216≈5.022147
Step5: Find PV
PV=50000/5.022147≈9955.90
Answer:
9955.90
