I assume you mean sales tax... I have not heard of spaces tax!
We add her purchases together ($149.95 + 59.00) and we get 208.95. Now we need to add 8% sales tax by mult by .08.
208.95 x .08 = 16.72 (rounded up from 16.716)
Add the sales tax to the total.
16.72 + 208.95 = 225.67 total purchase w/ tax
