Anne now has a balance of $1200 on her credit card, on which 1% interest per month is charged. Assume that she makes no further purchases or payments (and that the credit card company doesn\'t turn her account over to a bill collector).
(a) Find the rule of the function g that gives Anne\'s total credit card debt after x months

Solution

Interest charged = 1% of 1200 every month

After x months = x(1200*1/100) = 12x

So g(x) --Total credit debt after x months

g(x) = 1200 +12x
