Chapter SR10, Problem 19P

Solution

To write an algebraic expression that represents the amount Wendy spent.

  $10x$

Given:

Wendy bought 10 pens prices at x dollars each.

Concept Used:

• The term more indicates the addition operation.
• The term less/reduced is used for subtraction.
• The term times indicates the product.
• The term quotient represents the division.

Calculation:

Since she bought 10 pens prices at x dollars each, the total amount she spent can be obtained by multiplying the number of pens with the price of each pen.

So, the algebraic expression that represents the amount she spent is given by $10\cdot x\text{ or }10x$ .

Thus, the algebraic expression for the given phrase is $10x$ .
