## Part A
discount(2, 3)
Returns: 36

## Part B
discount(1,1) # Any arguments where they are equal
Returns: None
Should return: 13

## Part C
### Solution 1
def discount(hats, scarves):
    if hats > scarves:
        return scarves*13 + (hats-scarves)*5
    if scarves > hats:
        return hats*13 + (scarves-hats)*10
    return hats*4 + scarves*9 # Add this line or hats*13

### Solution 2

        return scarves*13 + (hats-scarves)*5
    else: # made this an else
