Answer 7

I wrote this code , apparently it works with certain inputs but won't work with others so i guess i am stuck .
houses = int(input())

s= 2 / houses * 100
print (round(s))

Answer 8

I did it,
int totalHouses = Convert.ToInt32(Console.ReadLine());

// Calculate the number of dollar bills received
int numDollarBills = 2;
int numToothbrushes = 1;
int numCandies = totalHouses - numDollarBills - numToothbrushes;

// Calculate the percentage chance of getting a dollar bill
double dollarChance = (double)numDollarBills / (double)totalHouses * 100;
int roundedDollarChance = (int)Math.Ceiling(dollarChance);
Console.WriteLine(roundedDollarChance);
