Chapter SR10, Problem 14P

Solution

To write an algebraic expression that represents the amount Ryan should get change.

  $20-x$

Given:

Ryan bought a movie ticket for x dollars. He paid with a $20 bill.

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:

Let x be the price of the movie ticket.

Since he paid a $20 bill, amount of change that he will receive must be equal to the difference of 20 and the price of the movie ticket.

So, the algebraic expression that represents the amount of change he will receive is given by $20-x$ .

Thus, the algebraic expression for the given phrase is $20-x$ .
