Susan bought 3 CDs that were each the same price. Including sales tax, she paid a total of $44.40. Of that total, $2.70 was tax. What was the price of each CD before tax?

the answer is c.) yes, [triangle]klp can be reflected across the line containing [line]kp and then translated so that p is mapped to m.

the reason is this:

looking at the triangles visually we can see they share the same features. using rigid transfromations we can reflect it over [line]kp then all we need to do is translate up.

the answer is actually 18%
