Answer:
$1600
Step-by-step explanation:
Before increase:
Jia Xin :Tiffany = 105 :100 = 21 : 20
After increasing both savings by 5%, their ratio remains unchanged.
Total savings = 21 + 20 = 41 units
41 units = $3280
1 unit = $3280 + 41 = $80
Jia Xin's savings after increase:
21 units $80 x 21 = $1680
Jia Xin's savings before increase: $1680 x 100/105 $1600
Jia Xin's savings before the increase was $1600.
hope i helped you po
