***Java***

Here is my code, but my tax is not calculating properly. This runs properly but the tax is not correct. It is supposed to be 7% or .07. I can get the amount to be correct if I assign the variable to the mcTax of .93, but I believe there is a better way to code this. I just want the tax (7%) to be figured on the SubTotal and then for the tax to be added to the Subtotal to reach the Total. There should be a better way to code this in Java. Thank you!
