Full box = X Candy Bars,
X - X/4 = 3X/4 Candy bars left,
(1/2)(3X/4) = 3X/8 Candy bars left,
(1/6)(3X/8) = 3X/48 = X/16 Candy bars left,
X/16 = 10 Candy bars,
Multiply both sides by 16:
X = 160 Candy bars to begin with.
X - X/4 = 3X/4 Candy bars left,
(1/2)(3X/4) = 3X/8 Candy bars left,
(1/6)(3X/8) = 3X/48 = X/16 Candy bars left,
X/16 = 10 Candy bars,
Multiply both sides by 16:
X = 160 Candy bars to begin with.
