What is wrong, if anything, with the statement below?
Answer true or false . If false, explain your reasoning.

If the interest is charged at 15% APR and is calculated according to the adjusted balance method, the amount of interest is $$\begin{aligned}I & = P r t \\& = \$ 950 ( 0.15 ) \left( \frac { 1 } { 12 } \right) \\& = \$ 11.875\end{aligned}$$ or (to the nearest cent) $11.88
