Answer:
Alice: 20 coins, Ben: 16 coins, and Carlos: 4 coins.
Explanation:
We know that the dive results in 40 gold coins.
We know that:
Alice: $7,600 Ben: $5,900 Carlos: $1,400.
So they have $ 14900 in total.
Now we will divide that money by 40.

So 1 gold coin costs $ 372.5. Now we will calculate how much they can get for the money they have.

We conclude that:
Alice: 20 coins, Ben: 16 coins, and Carlos: 4 coins.
