Holly has 20 balls, and there are 100 balls in total.
So there are 100-20 = 80 balls left.
Alex had 2 * the amount Holly had, which is 20.
So Alex has 20 * 2 = 40 balls.
Together, they have 60 balls.
Which means 100-60 = 40. So Ben has 40 balls.
Check:
Holly: 20
Alex: 40
Ben: 40
Add them: 20 + 40 + 40 = 100
Answer:
40 balls
Step-by-step explanation:
Let the number Ben has be A.
Holly , Alex and Ben had 100 balls.
Holly had 20
Alex had 2x holly = 2 x 20
= 40 balls
Therefore
20 + 40 + A = 100
60 + A = 100
Subtract 60 from both sides
60 - 60 + A = 100 - 60
A = 40
Ben had 40 balls
Check
Holly + Alex + ben
20 + 40 + 40
= 100 balls
