Rodney Reid · Answer 1

Compound interest is given by:

A=P (1+r/100) ^n

Amount Jenny earned after 5 years will be:

A=20000 (1+4.5/100) ^5

A=$24,923.64

Amount Cam earned:

A=20000 (1+6.5/100) ^5

A=$27,401.73

Comparing the two earnings we get:

27401.73-24923.64

=$2,478.09

We conclude that Cam had $2478 more money in the account than Jenny.
