Let x be the total number of the stickers. Then Andrew has; Blaze has and Cadmus has 20 stickers. With it, write the equation for the total + + 20 = x. To solve it, multiply both sides by 5 x + (x+50) + 100 = 5x. Simplify and find x 50 + 100 = 5x - x - x 150 = 3x x = 150/3 = 50. ANSWER. In all, there were 50 stickers.
