A librarian is expanding some sections of the city library. He buys book at a special price from a dealer who charges one price

stiks02 [169]

Answer:

The special price of 1 hardcover book = $13

The special price of 1 paperback book = $6

Step-by-step explanation:

Here, let us assume the special price of 1 hardcover book = $ m

and the the special price of 1 paperback book = $ n

Now, the price of 12 hardcover books = 12 x ( Price of 1 hardcover) = 12 m

and the price of 73 paperback books = 73 x ( Price of 1 paperback) = 73 n

Also, The price paid for 12 hardcover and 73 paperback books is $594

⇒ 12 m + 73 n = 594 ....... (1)

Similarly:

The price of 11 hardcover books = 11 x ( Price of 1 hardcover) = 11 m

The price of 87 paperback books = 87 x ( Price of 1 paperback) = 87 n

Also, The price paid for 11 hardcover and 87 paperback books is $665.

⇒ 11 m + 87 n = 665 ....... (2)

Now, solving both equation for the value of m and n , we get:

12 m + 73 n = 594 x 11

11 m + 87 n = 665 x (-12)

we get: 132 m + 803 n = 6534

- 132 m - 1044 n = - 7980

adding both equation, we get:

132 m + 803 n - 132 m - 1044 n = - 7980 + 6534

or, - 241 n = - 1446

or, n = 1446/241 = 6, or n = 6

Now, Substituting n = 6 in 12 m + 73 n = 594 ,

we get: 12 m + 73 ( 6) = 594, m = 13

Hence, The special price of 1 hardcover book = $13

and The special price of 1 paperback book = $6
