There is a total of 36 books on the bookshelf. The number of hardback books is 15 more than twice the number of paperback books.
uranmaximum [27]

The number of hardback books that are on the bookshelf is 29 books.

  • Let the total number of books be T.
  • Let the number of hardback books be H.
  • Let the number of paperback books be P.

<u>Given the following data:</u>

  • Total number of books = 36 books

To determine the number of hardback books that are on the bookshelf:

Translating the word problem into an algebraic expression, we have;

The total number of books is:

T = H+P

The number of hardback books is 15 more than <u>twice</u> the number of paperback books:

H =2P+15

Substituting the given parameters into the formula, we have;

36 = 2P+15+P\\\\36=3P+15\\\\3P=36-15\\\\3P=21\\\\P=\frac{21}{3}

P = 7 books

For number of hardback books:

H =2P+15\\\\H=2(7)+15\\\\H=14+15

H = 29 books
