A Cell Phone Company Charges $$ 40 40 40 $ Per Month For Unlimited Calling And $$ 0.20 0.20 0.20 $ Per Text Message Sent. If $t$ Represents The Number Of Text Messages Roxy Sent Last Month, Which Expression Represents The Cost
Introduction
In today's digital age, cell phone companies offer various pricing plans to cater to different customer needs. One such plan charges a fixed monthly fee for unlimited calling and an additional fee for each text message sent. In this article, we will explore the pricing model of a cell phone company that charges $40 per month for unlimited calling and $0.20 per text message sent. We will derive an expression that represents the total cost of text messages sent by a customer, such as Roxy, last month.
The Pricing Model
The cell phone company charges a fixed monthly fee of $40 for unlimited calling. This means that Roxy will pay $40 regardless of the number of text messages she sends. However, she will be charged an additional $0.20 for each text message sent. Let's assume that Roxy sent t text messages last month. The cost of these text messages can be calculated as follows:
- The cost of unlimited calling is $40.
- The cost of each text message is $0.20.
- The total cost of text messages sent is the product of the cost per text message and the number of text messages sent, which is $0.20t.
Deriving the Expression
To derive the expression that represents the total cost of text messages sent by Roxy last month, we need to add the fixed monthly fee for unlimited calling and the cost of text messages sent. This can be represented mathematically as:
Total Cost = Fixed Monthly Fee + Cost of Text Messages = $40 + $0.20t
Simplifying the Expression
We can simplify the expression by combining the constant terms:
Total Cost = $40 + $0.20t = $40 + 0.20t
Understanding the Expression
The expression $40 + 0.20t represents the total cost of text messages sent by Roxy last month. The variable t represents the number of text messages sent, and the coefficient 0.20 represents the cost per text message. The constant term $40 represents the fixed monthly fee for unlimited calling.
Example
Let's consider an example to illustrate how the expression works. Suppose Roxy sent 50 text messages last month. The total cost of these text messages can be calculated as follows:
Total Cost = $40 + 0.20(50) = $40 + $10 = $50
In this example, the total cost of text messages sent by Roxy last month is $50.
Conclusion
In conclusion, the expression $40 + 0.20t represents the total cost of text messages sent by Roxy last month. The variable t represents the number of text messages sent, and the coefficient 0.20 represents the cost per text message. The constant term $40 represents the fixed monthly fee for unlimited calling. This expression can be used to calculate the total cost of text messages sent by a customer, such as Roxy, last month.
