1 u |
4 u |
Total amount that Tina and Victoria had at first
= 5 u + 4 u + 35
= 9 u + 35
9 u + 35 = 800
5 u + 4 u = 800 - 35
9 u = 765
1 u = 765 ÷ 9 = 85
Amount that Tina had at first
= 5 u
= 5 x 85
= $425
Amount that Victoria had at first
= 800 - 425
= $375
At first
Tina : Victoria
425 : 375
17 : 15
Answer(s): 17 : 15
