Roni has 25 sweets and Tony has 55 sweets. How many sweets should Roni give to Tony so that Tony has four times as many sweets as Roni?
- 5
- 7
- 9
- None of these
Explanation
Let the number of sweets Roni gives to Tony be x.
After giving x sweets: Roni will have 2 25−x sweets.
Tony will have 55+x sweets.
We want Tony to have four times as many sweets as Roni, so: 55 + x = 4 ( 25 − x )
Expand the equation:
Add to both sides to combine the -terms:
Subtract 5 from both sides:
Solve for :
x = 45/ 5 = 9 x
