Answer:
50.35$
Step-by-step explanation:
Tax is simply the additional percentage that you have to pay compared to the normal price. If 100% of the price is 47.95$, we need to calculate what is 105% of 47.95 is since with tax it is 100+5. So 105% * 47.95 = 50.35$
The same principle works with discounts. If lets say you have a 10% discount on the textbook, you do 100-10 = 90%, so the new price is 90% the original price so 90%*47.95 = 43.16$
