Joe’s cell phone costs him $21 per month plus $3 for every 1GB of data downloaded. What is the limit to the number of GBs he can download to stay within his monthly budget of $30.

amount of money he's left with after paying for his cell phone cost:
$30-$21=$9

with the $9 he has left, you divide it by $3 (1GB) to get the number of GBs he can get per month
$9÷$3=3GB
