Round 208 of Neopets 'Lenny Conundrum': Find two numbers...

[shygirl1083]

While exploring through the trading post, you find someone offering a Ghostkerbomb. When you ask what she wants for it, this is her reply:

"Suppose you have two numbers. The difference of the two numbers is 12. The product of the two numbers is 17. Multiply the larger of the two numbers by 100, add 50 times the smaller number to that, round the total to the nearest whole number, and that's my price."

Since this isn't a math question, but is a contest puzzler. Since the contest is open until 28 March, and in light of Round 148, it wouldn't be legitimate to post any solution until after the contest closes and prizes have been awared.

Contrary to the practice at most tutoring forums, Neopians are not immediately banned at FreeMathHelp. If you would like to work on the mathematics of this contest riddle, we will be glad to work with you on that. But you'll need to show some effort of your own.

Thank you.
