The formula for compound interest is:
Given data:
a. After ten years, that is t = 10 years, the amount in the account will be
b. After twenty years, that is t = 20 years, the amount in the account will be:
c. The time it takes for Harry's initial account value to double will be:
Therefore, the time it takes Harry's initial account to double is approximately 11 years
Let the number of boys be b, the number of girls be g and that of teachers be t,
thus:
b=kg/t
where k is the constant of proportionality
k=bt/g
b=24, when g=16 and t=2
k=(24*2)/16
k=3
hence:
b=(3g)/2
thus the number of girls when:
b=73 and t=1 will be:
73=(3*g)/1
73=3g
g=73/3
g=24.333~ 24 girls
