The precise equation that represents the situation is as follows:
His cell phone plan provides 300 free minutes each month for a flat rate of $19.
let
x = number of minutes used
Therefore,
$19, x ≤ 300
For any minutes over 300, Andrew is charged 0.39 per minute.
if x > 300
f(x) = 19 + 0.39(x - 300)
