Answer:
The rate is [tex]\frac{1.92}{3}[/tex]
Step-by-step explanation:
This question can be solved by a rule of three.
A long-distance phone call between two cities costs $1.92 for 3 minutes. What is the rate in cents per minute?
3 minutes costs $1.92. How much does one minute cost?
3 minutes - $1.92
1 minute - $x
[tex]3x = 1.92[/tex]
[tex]x = \frac{1.92}{3}[/tex]
