If the sales-tax rate is 7.5%, what is the sales tax on a $48.00 purchase?

The tax is 3.60, the total is 51.60

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.
