8.91 $
Step-by-step explanation:
First you need to get rid of the 50 cents for each book and there's 5 books so it's 2.50 for all of them
95.19-2.50= 92.65
Next get rid of the tax
92.65 x 0.038 (decimal version of 3.8%)= 3.52 (the amount of tax April paid)
92.65-3.52= 89.13
Now get rid of the 10% for each book or 50%
89.13 x 0.5 = 44.565
Divide by 5 for each book and you have the prices of the book after the sale which is 8.913 or 8.91 $
The prices of each book before the sale were 17.83 if you needed to know
