A: 40
Let’s do this problem backwards.
TOTAL BOOKS RN: 36
1)
“Jill... then bought 16 more...”
36 - 16 = 20
After subtracting that amount, we would end up with half of the books Jill DID NOT sell.
2)
2 • 20 = 40
At this point, we multiplied amount of books she had after she sold half of her comic books by the reciprocal of 1/2
And now you have your answer!
I'm sorry, I don't see the question. Could you please retake the photo in better quality so I could answer it? Thanks!
First find out what 10 percent of 50 is
Do 50/10
I got 5
Then do 5 times 9 to get your answer
You should get 45. Thanks (:
