Answer:
40 times
Step-by-step explanation:
The bucket can carry 1/2 pounds of sand and Ms.Campbell purchased 20-pound bag of colored sand,so if 1/2+1/2=1 then than amount of times that Ms.campbell needs to carry the sand will be doubled from the pounds of a bag of colored sand,
So that means 20/1/2 or 20*2 for short and the answer would be 40
