Answer:
The correct amount is C. $43.75
Explanation:
In order to find the amount of money that they will have left, start by looking at what fraction of the original winnings they will still have. Since they spent 3/8 of them, we know he has 5/8 left.
So, we can multiply the amount of winnings by the fraction to get the total amount left over.
$70 * 5/8 = $43.75
