Question

Jane spent rupees 42 for shoes. This was rupees14 less than twice what she spent for a blouse. How much was the blouse?

Answer 1

Answer:

Rs.28

Step-by-step explanation:

Let the cost of the blouse be 'b'.

The equation will be:

2b-14=42

2b=42+14

2b=56

b=56/2= Rs.28

Answer 2

Every word problem has an unknown number. In this problem, it is the price of the blouse.  Always let x represent the unknown number.  That is, let x answer the question.

Let x, then, be how much she spent for the blouse.  The problem states that "This" -- that is, $42 -- was $14 less  than two times x.

Here is the equation:

2x − 14  =  42.

 

2x  =  42 + 14   (Lesson 9)

 

  =  56.

 

x  =  56

2

 

  =  28.
