Alex is saving money to buy a new bicycle that costs $300. He decides to save a fixed amount of money every day from his daily allowance. If Alex saves $5 every day, how many days will it take for him to save enough money to buy the bicycle? Additionally, if Alex decides to save an extra $2 on weekends (Saturday and Sunday), how many days will it take him to save the $300? Let's think step by step and output the final answer within \boxed{}.
