Answer:
48 dollars
Explanation:
Total money of Grant : 36
Total money of John : 12
Grant gave 9 dollars to John : 36 - 9 = 27
Now John has 21 dollars ( 12 + 9 = 21 )
So , 21 + 27 = 48
Thus , John and Grant have 48 dollars in total
grant originally had 36 and john had 12
decrease grant by 9 and increase john by 9
grant has 27, and john has 21
difference is 6 so the sum is 48.
