David has run into some debt problems. He currently has the following credit card debt and can only pay $$\frac{250}{?}$ month.

Which strategy below will save him the most on interest expense?

Pay the minimums on cards $2$&$3$ and everything else pay toward Card #$1$

Transfer Card #$1$ balance to Card #$3$ and then pay the minimum on Card #$3$ while paying everything else on Card #$2$

Pay the minimums on cards $1$&$2$ and everything else pay toward Card #$3$ so he can pay it off quickly and build some

momentum

Pay the minimums on Cards #$1$ and #$3$ and pay everything else on Card #$2$ since it has the highest outstanding balance
