$$7063.91=4251(1+\frac{0.034}{n})^{15n}$$
Now you need to solve for n which is the number of times the interest compounds in a year.

What would n be?

To find n you could try substituting 4 in the right hand side and calculate to see whether you get 7063.91. This value of n corresponds to quarterly compounding of interest.
