Erica->100

Robin->130
Charles->160

130+x/100*130 = 160

x~= 23

A

R = 1.3 E

C= 1.6 E

1.3 E * (1+x) = 1.6 E
or x = 0.233 ~ 23% A

CRamya, Bmlaud-

Can you please explain- This seems quite straightforward; however I am missing some correlation.

I understood the first 2 steps that you both did. I did not understand the last 2 steps of your soln.

Best regards,
Kanha
