Hi ghostdna,

This is a percentage problem and requires the equation: part/whole = percentage/100


Here your whole is $200 and you are give your percentage, so you must solve for your part.

When we rewrite our equation, it becomes:

part/200 = 1.2/100

Now we solve the right hand side

part/200 = .012

To find the part, we move the 200 over by multiplying it

part = 200 * .012

part = 2.4

So Roderick's finance charge will be $2.40
