4 u |
Total amount that Jane and Jaslyn had at first
= 5 u + 4 u + 33
= 9 u + 33
9 u + 33 = 465
5 u + 4 u = 465 - 33
9 u = 432
1 u = 432 ÷ 9 = 48
Amount that Jane had at first
= 5 u
= 5 x 48
= $240
Amount that Jaslyn had at first
= 465 - 240
= $225
At first
Jane : Jaslyn
240 : 225
16 : 15
Answer(s): 16 : 15
