Question

Q. A book costs $1 plus half its price. How much does it cost?​

Answer 1

Let the cost of book be x.

A/Q,
x = $1 + (x/2)

=> x - (x/2) = $2

=> (2x - x)/2 = $1

=> x/2 = $1

=> x = $1 × 2

=> x = $2

Therefore, the cost of the book is $2.

Answer 2

Given:

A book costs $1 plus half its price.

To Find:

The price of the book is?

Solution:

1. Let the price of the book be x $.

2. As the price of the book is $1 more than half of its price, Equationally it can be written as,

=> x = 1 + (x/2), ( Solve the equation for the value of x )

=> x = (2+x)/2,

=> 2x = 2 + x,

=> 2x - x = 2,

=> x = 2.

3. Price of the book = $2.

Therefore, the price of the book is $2.
