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 $\$28$.
