Question

What is the amount of pieces in each color

Answer 1

brown = 12

yellow = 30

orange = 36

Explanation:

let 'b' = # brown

let '18+b' = # yellow

let '3b' = #orange

add them together and set equal to 78

b + 18 + b + 3b = 78

5b + 18 = 78

5b = 60

b = 12

y = 12 + 18 = 30

o = 3(12) = 36

12 + 30 + 36 = 78
