Answer to Problem 58AYU

The blouse cost is $28 .

Explanation of Solution

Given:

Make up a word problem that requires solving a linear equation as part of its solution. Exchange problems with a friend.

Calculation:

Jane spent $42 for shoes. This was $14 less than twice what she spent for a blouse. How much was the blouse?

The solution is every word problem has an unknown number. In this problem, it is the price of the blouse.

Always let x represent the unknown number.

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 the equation,

2x  14 = 42

2x = 56

x = 28

So the blouse cost is $28 .
