If you put $2000 into an interest bearing account, where interest is compounded quarterly (4 times a year) at 6%, how long will it take for your money to triple? solve for t (years)

25,600

Step-by-step explanation:

You can use the rule of three considering that the number of dolls sold varies directly with the advertising budget:

$54,000    →   9,600

$144,000   →       x

x=25,600

According to this, the number of dolls sold if the amount of advertising budget is increased to $144,000 is 25,600.
