Question

Angie, Keisha and Chen shared 125 stickers among themselves. Keisha and Chen received an equal number of stickers and Angie received one less sticker. How many stickers did Keisha receive?

Answer 1

42 stickers

Explanation:

Let

x = number of stickers Keisha and chen received

x - 1 = number of stickers Angie received

Total stickers = 125

125 = x + x + (x - 1)

125 = 2x + x - 1

125 + 1 = 3x

126 = 3x

x = 126/3

x = 42 stickers

x = number of stickers Keisha and chen received = 42 stickers

x - 1 = number of stickers Angie received = 42 - 1 = 41 stickers
