Just put a period between everything 2.9.3.3
Present value, P = 950
interest rate, i = 6.5% continuous
Number of periods, n = 10 years
Future value



to the nearest cent
Maria = x
Tom = y
Use substitution
x+y=30
2y=x
2y+y=30
3y=30
y=10
Tom is 10 years old.
x+y=30
x+10=30
x=20
Maria is 20 years old.
X=3%h I think I'm not to sure hope that helped! Good Luck!!!
