Ivory and Fanny had the same amount of money at first. After Ivory gave $180 to her nephew, Fanny had 7 times as much money as Ivory. How much did Ivory have in the end?

| Before |
1x7 =

1x7 =
7 u |

- $180 |

| After |
1 u |
7 u |
The amount that Fanny had at first and in the end remains unchanged. Make the amount that Fanny had the same. LCM of 1 and 7 is 7.
Amount that Ivory gave to her nephew
= 7 u - 1 u
= 6 u
6 u = 180
1 u = 180 ÷ 6 = 30
Amount that Ivory had in the end
= 1 u
= $180
Answer(s): $180
