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
⇒ [tex]x+y = 6.28 ----- (1)[/tex]
The notebook cost $0.70 more than the pencil box,
⇒ [tex]y=x+0.70 ----- (2)[/tex]
Now substitute equation 2 in equation 1,
⇒ [tex]x+x+0.70=6.28[/tex]
⇒ [tex]2x=6.28-0.70[/tex]
⇒ [tex]x=\frac{5.58}{2}[/tex]
⇒ [tex]x=2.79[/tex]
∴ [tex]y=6.28-2.79[/tex]
⇒ [tex]y=3.49[/tex]
Hence we can conclude that the cost of notebook is $3.49.
