**drwls**, Friday, June 10, 2011 at 2:35amIt's spelled nickels.

Let x = number of nickels (originally)

let y = number of dimes (originally)

5x + 10y = 765

5*(x + 35) + 10*(2y) = 1430

5x + 20y = 1430 - 175 = 1255

The x terms are easily eliminated

10 y = 490

y = 49

5x = 765 - 490 = 275

x = 55
