Question

C = number of stamps collected by Callie. Jenna and Callie collect stamps. Jenna has 20 less than twice the number of stamps that Callie has. Which expression represents the number of stamps that Jenna has?

A) 2c + 20
B) 2c - 20
C) 20 - 2c
D) 20 + 2c

Answer 1

The correct expression representing the number of stamps Jenna has is 2c - 20, where c is the number of stamps collected by Callie.

Step-by-step explanation:

The question is asking to find an expression that represents the number of stamps Jenna has if she has 20 less than twice the number of stamps that Callie has. The number of stamps collected by Callie is represented by the variable c. To get the number of stamps Jenna has, we would take twice the amount Callie has, or 2c, and subtract 20 from it. Therefore, the correct expression for the number of stamps that Jenna has is 2c - 20.
