Hey /sci/ any mathfags on? I need help with this story problem for class and im pretty bad at these kind of problems so if you could just help me get it into an equation then I would be able to solve it myself. So here's the question:

Judah cracks open a piggy bank and finds $3.33 (330 cents), all in nickels and dimes. There are 15 more dimes than nickels . How many nickels does Judah have?
