5x9 = 45 u |
Change |
- 1x2 = - 2 u |
- 3x9 = - 27 u |
After |
9x2 = 18 u |
2x9 = 18 u |

110 Wendy and Elyse had the same amount of money in the end. Make the amount that each had in the end the same. LCM of 2 and 9 is 18.
Amount that Wendy had less than Elyse at first
= 45 u - 20 u
= 25 u
25 u = 625
1 u = 625 ÷ 25 = 25
Amount that Elyse had at first
= 45 u
= 45 x 25
= $1125
Answer(s): $1125
