Anybody know the answer? if you do you'll get 10 points!

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
