**drwls**, Friday, January 16, 2009 at 4:42pmWrite equations for the total number sold and the total sales dollars. This will let you solve for the two unknown amounts sold, W and Y.

W + Y = 35

9.95 W + 12.50 Y = 389.05

Substitute 35-Y for W in the second equation and solve for Y.

9.95 (35 - Y) + 12.50 Y = 389.05

2.55 Y = 389.05 - 348.25 = 40.80

Y = ?
