The card that accrues the most interest is the second one, "Cred". To find those amounts multiply the rate by the balance and divide by 12.
Lol
trouble varies directly as distance
lets say t=trouble and d=distance
t=kd
k is constant
given
when t=20, and d=400
find k
20=400k
divide by 400 both sides
1/20=k
t=(1/20)d
given, d=60
find t
t=(1/20)60
t=60/20
t=3
3 troubles
20+2N=52
now subtract 20 from each side, to get 2N alone
2N=32
now divide each side by 2
N=16
