**Reiny**, Thursday, October 27, 2011 at 8:29amI will do the first, you do the second

number of $19's --- x

number of $26's --- x-3

number of $23's --- 32 - x - (x-3) = 35-2x

19x + 26(x-3) + 23(35-2x) = 716

19x + 26x - 78 + 805 - 46x = 716

-x = -11

x = 11

he sold 11 of the $19's

8 of the $26's and

13 of the $23's
