n = [(z-value * sd)/E]^2

...where n = sample size, z-value will be 2.58 using a z-table to represent the 99% confidence interval, sd = 535, E = 137, ^2 means squared, and * means to multiply.

Plug the values into the formula and finish the calculation. Round your answer to the next highest whole number.
