**Ms. Sue**, Monday, September 10, 2012 at 8:16pmYour answer is obviously wrong. She bought 3 collars. If she paid 63 for one collar -- then she would have paid 189 for three.

**Ms. Sue**, Monday, September 10, 2012 at 8:31pmLet's check:

(3 * 21) + (5 * 7) = 98

Nope -- you're getting closer.

**Ms. Sue**, Monday, September 10, 2012 at 8:53pmI don't know. I found the right answer by trial and error.

**Reiny**, Monday, September 10, 2012 at 9:09pmcost of bone --- x

cost of collar --- 3x

5 bones + 3 collars = 84

5x + 3(3x) = 84

14x = 84

x = 84/14 = 6

cost of bone = $6

cost of collar = 3(6) = $18
