They will see each other every 30 days but won't every 15 days
Owes more than 1425
owe>1425
owed musbe be equal to how much he paid back
paid back 210
and 153 per month is paid back (represent number of months by x)
so
owe=210+152x
210+153x>1425
153x+210>1425
Don't know if this is right or if it helps but
