Answer:
$252
Explanation:
Step 1
Toy has $36 and gets $36 from Ami. Now he has $36*2= $72
Step 2
Toy gets $72 from Jan to double his money and now has $72*2= $144
Step 3
Toy gives enough money to Ami and Jan to double their money
Toy has $36 at the end, so he has given $144 - $36= $108 to Ami and Jan
Since he doubles their money by giving $108, they now have
Now we add the amount Toy has at the end to the amount Ami and Jan have at the end to get final amount:
So the friends have $252
