To write an equation for the monthly cost \( c \) based on the number of text messages \( t \) sent, you can combine the fixed monthly charge with the variable cost of text messages.
The fixed monthly charge is $30, and the variable cost is $0.05 multiplied by the number of text messages \( t \).
The equation can be written as:
\[
c = 30 + 0.05t
\]
In this equation:
- \( c \) is the total monthly cost,
- \( 30 \) is the fixed monthly fee,
- \( 0.05t \) is the cost based on the number of text messages sent.
The fixed monthly charge is $30, and the variable cost is $0.05 multiplied by the number of text messages \( t \).
The equation can be written as:
\[
c = 30 + 0.05t
\]
In this equation:
- \( c \) is the total monthly cost,
- \( 30 \) is the fixed monthly fee,
- \( 0.05t \) is the cost based on the number of text messages sent.
