Фундаменталс решение:

junior = int(input())
senior = int(input())
trace = input()

junior_price = {'trail': 5.5, 'cross-country': 8, 'downhill': 12.25, 'road': 20}
senior_price = {'trail': 7, 'cross-country': 9.5, 'downhill': 13.75, 'road': 21.5}

total = junior * junior_price[trace] + senior * senior_price[trace]

if trace == 'cross-country' and (junior + senior) >= 50:
    total *= 0.75

print(f'{(total * 0.95 ):.2f}')
