1. Let $$ x $$ be the call rate in cents per minute.

2. Since it costs 45 cents for 15 minutes, we have:
   $$
   15x = 45
   $$

3. To find $$ x $$, divide both sides of the equation by 15:
   $$
   x = \frac{45}{15}
   $$

4. Simplify the fraction:
   $$
   x = 3
   $$

Thus, the call rate is $$ 3 $$ cents per minute.
The call rate is 3 cents per minute.
