Yen and Kimberly had the same amount of money at first. After Yen gave $700 to her niece, Kimberly had 8 times as much money as Yen. How much did Yen have in the end?
| |
Yen |
Kimberly |
| Before |
1x8 =
8 u |
1x8 =
8 u |
| Change |
- $700 |
|
| After |
1 u |
8 u |
The amount that Kimberly had at first and in the end remains unchanged. Make the amount that Kimberly had the same. LCM of 1 and 8 is 8.
Amount that Yen gave to her niece
= 8 u - 1 u
= 7 u
7 u = 700
1 u = 700 ÷ 7 = 100
Amount that Yen had in the end
= 1 u
= $700
Answer(s): $700
