Understanding Math equations

I’ve two screen shots from lesson 6 in the 14 day course.

When solved the problem it was different from the solution. Getting the tax amount confuses.


Not done this course, but happy to help. The second image is another way to reach the same result. By adding 1 to the tax of 0.13 you’re getting 1.13, which is the number the subtotal needs to be multiplied to get the net amount including the tax. Its shorter that saying subtotal + (subtotal * 0.13)

Hope that helps.

Of course! Some things are too easy to see. Thanks!
