Eva and Jean went shopping with a total of $336. After Eva spent
34 of her money and Jean spent $21, the ratio of Jean's money became 5 times as much as Eva's money. Find the ratio of Eva's money to Jean's money at first.

| Comparing between Eva and Jean in the end |
1 u |
5 u |
Total amount that Eva and Jean had at first
= 4 u + 5 u + 21
= 9 u + 21
9 u + 21 = 336
4 u + 3 u = 336 - 21
9 u = 315
1 u = 315 ÷ 9 = 35
Amount that Eva had at first
= 4 u
= 4 x 35
= $140
Amount that Jean had at first
= 336 - 140
= $196
At first
Eva : Jean
140 : 196
5 : 7
Answer(s): 5 : 7
