You can put this solution on YOUR website! A=60+.25X
B=250+.20X
60+.25*350=50+$87.50 IS HER PAYMENT.
250+.20*350=250+70=$320 IS HER PAYMENT.
----------------------------------------
60+.25X>250+.20X
.25X-.20X>250-60
.05X>190
X>190/.05
X>$3,800 IS THE BREAKEVEN POINT ABOVE WHICH PLAN B IS A BETTER DEAL.
PROOF:
LET X=3,850
60+.25*3,850>250+.20*3,850
60+962,5>250+770
1,022.5>1,020
