Ok, she pays a monthly fee of 25, so start off the inequality with 25. They charge .05 for every minute, so then put + .05m. That is the left side of the inequality. The right side will be the least she has been charged, 77.3. Now, since that is the least she was charged the inequality sign will be greater than or equal to.
$\sf 25~+~.05m~\ge~77.3$
