Students sold books to the local library as a part of a school drive. paper books were brought for $1.45 each. The library spent $98.60 on paper books . Hardback books were brought for $2.25 each. The library spent $328.10 buying used books. How many books did the library purchase?

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)
