What is a word problem?
A word problem is a verbal **description **of a problem situation. It consists of few sentences describing a ' real-life ' scenario where a problem needs to be solved by way of a **mathematical **calculation.
For the given situation,
Let the **cost **of **pencil **box be x
Let the **cost **of **notebook **be y
Total **cost **= $6.28
⇒ x + y = 6.28 − − − − − ( 1 )
The **notebook cost **$0.70 more than the **pencil **box,
⇒ y = x + 0.70 − − − − − ( 2 )
Now substitute equation 2 in equation 1,
⇒ x + x + 0.70 = 6.28
⇒ 2 x = 6.28 − 0.70
⇒ x = 2 5.58 ​
⇒ x = 2.79
∴ y = 6.28 − 2.79
⇒ y = 3.49
Hence we can conclude that the cost of **notebook **is $3.49.
