5 u |
Total amount that Zara and Cindy had at first
= 6 u + 5 u + 50
= 11 u + 50
11 u + 50 = 600
6 u + 5 u = 600 - 50
11 u = 550
1 u = 550 ÷ 11 = 50
Amount that Zara had at first
= 6 u
= 6 x 50
= $300
Amount that Cindy had at first
= 600 - 300
= $300
At first
Zara : Cindy
300 : 300
1 : 1
Answer(s): 1 : 1
