Answer:
The cost of each DVDs is $ 13 .
Step-by-step explanation:
Given as :
The cost of earphones = $ 10
The number of DVDs bought = 3
The total cost of both items before tax = $ 49
Let The cost of each DVDs = $ x
So, According to question
The cost of earphones + The cost of 3 DVDs = $ 49
Or, $ 10 + 3 × x = $ 49
Or, 3 × x = $ 49 - $ 10
Or, 3 × x = $ 39
∴ x = [tex]\frac{39}{3}[/tex]
I.e x = $ 13
Hence The cost of each DVDs is $ 13 . Answer
