Adam has $450. he spends $210 on food. later he divides all the money into four parts out of which three parts were distributed and one part he keeps for himself. then he found $50 on the road. write the final expression and find the money he has left?

To answer this item, we let x be the amount of money he has left that was initially part of the total $450.

First, subtract $210 from it (spent by Adam on food)
         $450 - $210 = $240

Then, divide the remaining amount of money by 4
           $240 / 4 = $60

Since, it was only one part that he kept to himself, the amount of money left with him, x, is
                       x = $60

Then, the total amount of money he has including that which he only picked from the road is,
             T = $60 + $50 = $110

In the end, Adam had $110.
