That is only 33.48 megabytes.
But your error is before that.
3600 * 24 * 31 = 2678400 sec/month (that one you got right)
2678400 sec/month * 100,000,000 bits/sec = 267,840,000,000,000 bits/month (you had an error here)
267,840,000,000,000 bits/month / 8 bits/byte = 33,480,000,000,000 bytes/month
33,480,000,000,000 bytes/month / 1,000,000,000 bytes/gigabyte = 33,480 gigabytes/month
33,480 gigabytes/month * 15 $/gigabyte = $502,200
