Your bill will be 24.63 USD

#### Explanation:

Since you have a fixed rate for a month (which is 15.99 USD) and time dependent variable, your equation will be:

$15.99 + \left(0.18 \cdot t i m e\right)$ If you talk total 48 minutes in a month:

$= 15.99 + \left(0.18 \cdot 48\right)$
$= 15.99 + 8.64$
$= 24.63$ USD
