Kaylee has $0.90 worth of nickels and dimes. She has a total of 10 nickels and dimes altogether. Determine the number of nickels, x, and the number of dimes, y, that Kaylee has.

Nickels are worth $0.05 and dimes are worth $0.10 so if nickes + dimes = 10 and $0.05*nickels + $0.10*dimes = $0.90, then there are 2 nickels and 8 dimes.

 

Hope it helps!
