Answer:
144
Step-by-step explanation:
(81 - 9) * 2 = 144
work backwards, you now have 81 books. But you bought 9, so pretend you didn't buy the 9, means you would have 9 less books. so 81-9.
Then you multiply by 2 because originally you sold half of the books, so before you sold half, you had double the amount, so you multiply that by 2.
Answer:
10 2/3 is ther answer simplified
You would need the table to figure this problem out, but here we go!
15000×.018= 270
15000×.020= 300
15000×.023= 345
270+300+345= $915
X= -3
