3 1/3 would be the answer
Answer:
213 books
Step-by-step explanation:
Paper books = $1.45 each
$ 1.45 = 1 paper book
$ 1 = 1/1.45 paper book
$98.6 = 98.6/1.45 paper books
$ 98.6 = 68 paper books
Hardback books = $ 2.25 each
$2.25 = 1 Hardbook
$1 = 1/2.25 hardbook
$ 328.10 = 328.10/2.25 hardbooks
$ 328.10 = 145.822 hard books
Number of books cannot be a decimal number, so the value has to be estimated to a nearer whole number.
$ 328.10 = 145 hard books
Total number of books bought = (145 + 68)books= 213 books (Answer)

alogₓb=logₓbᵃ
logₐaˣ=x
logₐa=1
log(ab)=loga+logb
logₐx=y means a^y=x
3log₃6=log₃216=log₃(2³ times 3³)=log₃(2³)+log₃(3³)=log₃(8)+3
answer is log₃(8)+3 or 3(log₃(3)+1)
9n + 15 < = 10n + 24
9n - 10n < = 24 - 15
-n < = 9
n > = -9
