Darren has borrowed 100 clams from Ethan at a 10% simple daily interest. Meanwhile, Fergie has borrowed 150 clams from Gertie at a 6% simple daily interest. In how many days will Darren and Fergie owe the same amounts, assuming that they will not make any repayments in that time period?

100  + 100 (.10) t   =  150 + 150  (.06)  t

 

100  +  10t   =  150  +  9t

 

10t - 9t   = 150  - 100

 

t  =  50    days
