Formula for continuous compounding: A=Pe^rt, P=initial investment, r=interest rate, A=amt after t-years
100,000=Pe^.04*30
P=100,000/e^1.2=$30,119.42
What amount should she invest now to achieve this goal?$30,119

Model y=p%2Ae%5E%280.04%2At%29 and you will later use y=100000 and t=30.

p=y%2F%28e%5E%280.04%2At%29%29

Substituting the values and resorting to a scientific calculator or other equipped resource,
p=100000%2F%28e%5E%280.04%2A30%29%29

p=100000%2Fe%5E%281.2%29

highlight%28p=30120%29-----Initial investment amount.
