Working with a Piecewise Function

A cell phone company uses the function below to determine the cost, $C,$ in dollars for $g$ gigabytes of data transfer.

$C (g) = {25 25 + 10 (g - 2) if if 0 < g < 2 g \geq 2$

Find the cost of using 1.5 gigabytes of data and the cost of using 4 gigabytes of data.
