Add tax to the final cost in the python $4x.$ py program and save the new program as python $5x.$py$.$ Assume that the tax rate is $6\mathrm{.}25\%.$ The final output should include the discounted cost plus $6\mathrm{.}25\%$ tax. Run the program to verify your code. Hint: The code cost $=cost+(.0625**$ cost$)$ can help here.
