Help me with this please

The equation that we need to use to answer the question above is,
                           I = P x ((1+r)^t) - P
where P is the principal amount, r is the interest rate (in its decimal equivalent) and t is time. Substituting the known values from the given,
                          I = ($2,530.16) x ((1 + 0.042/100)^30) - $2,530.16 
                                 I = $32
The nearest answer should be letter C.
