I want to buy coloring booksThe big coloring books have 100

I want to buy coloring books.The big coloring books have 100 pages for $8 while the small coloring books have 25 pages for $2. I want to pay $28 and got a total of 650 pages.How many each should i buy?

Solution

The cost of 100 pages for big coloring book is $8.

The cost of 1 page for big coloring book is $8/100 =$0.08.

The cost of 25 pages for small coloring book is $2.

The cost of 25 page for small coloring book is $2/25 =$0.08.

The cost of the 1 page for both the books is equal.

Number of pages that can be bought from $28 is = 28/0.08 =350.

Therefore, there is no possibily for buying 650 pages out of $28.
