15 Rhonda has $1.35 in nickels and dimes in her pocket. If
she has six more dimes than nickels, which equation can be used
to determine x, the number of nickels she has?

(1) 0.05(x + 6) + 0.10x = 1.35

(2) 0.05x + 0.10(x + 6) = 1.35

(3) 0.05 + 0.10(6x) = 1.35

(4) 0.15(x + 6) = 1.35

This is one of the absolute best sites I've found online, and I say that as a teacher who has spent countless hours looking for kid-friendly material on the net. I have no idea how you found the time and energy to put it together, but you have my admiration! - Andrew Cowells, Concord Jr. High
