8) A company sells small and large photo books. Each page of a small photo book costs
Dennis_Churaev [7]

38 pages of the book will cost $57.

Data;

  • number of page = 20
  • cost = $30

<h3>Proportions</h3>

To solve this question, we have to know the cost of one page of the book.

In the first scenario, 20 pages cost $30, let's find the cost of one page here.

20 page = \$30\\1 page = x\\x = \frac{30}{20}\\x = 1.5

We can confirm our answer here by testing with the second scenario;

32 page = \$48\\1page = y\\y = \frac{48}{32} = 1.5

Now can say that one page of the book cost $1.5, let's divide 57 by this to determine the number of pages

z = \frac{57}{1.5} \\z = 38

From the calculations above, 38 pages of the book will cost $57.
