Ken's savings was 2/5 of Edwin's savings. After Ken increased his savings by 20% and Edwin's savings decreased by 55%, Ken's savings was $600 more than Edwin's. What was Ken's savings in the end?
+237 K=2/5*E
2/5*E*1.2-600=E*.45
.48*E-600=.45*E
600=.03*E
E=20000
You can work out Ken's savings in the end by yourself :)
+237 Let x be Edwin's savings
2/5x be Ken's savings
2/5x + 20%(2/5x) + x - 55%x + $600
0.4x + 0.08x = 0.45x + $600
0.48x - 0.45x = $600
0.03x/0.03 = $600/0.03
x = $20000
2/5 ($20,000) + 20% (2/5($20,00)) = $9600
