Решение с тернарен оператор:

budget = float(input())
fuel = float(input())
day = input()

total = (fuel * 2.1 + 100) * (0.9 if day == "Saturday" else 0.8)

print(f"Safari time! Money left: {budget - total:.2f} lv. " if budget >= total
      else f"Not enough money! Money needed: {total - budget:.2f} lv.")


Тарикатско решение:)

total = float(input()) - ((float(input()) * 2.1 + 100) * (0.9 if input() == "Saturday" else 0.8))

print(f"Safari time! Money left: {total:.2f} lv. " if total >= 0 else f"Not enough money! Money needed: {abs(total):.2f} lv.")
