Renting a car cost 30dollars a day, or 600 per month. Renting daily is cheaper for a few days, but after how many days are the two options equal. (After which renting is cheaper)

Answer: The two options are equal after 20days of daily pay.

Step-by-step explanation:

If it cost $30 to rent a car for a day and $600 to rent the same car for a month (approximately 30days), renting daily is equal to the monthly rentage after 20 days ($30 for 20days which is $30*20 i. e $600)

According to the deduction above, the renting is cheaper daily only for the first 20 days after which the amount equals to the monthly rentage of the same car.

20 days.

Step-by-step explanation:

Assume, 1 month = 30 days.

Options:

i. $600 per month

$600/month * 1 month/30 day

= $20 per day.

ii. $30/day.

Renting daily is equal to the monthly rent after 20 days ($30 for 20days which is $30*20 i. e $600)

That is, the renting is cheaper daily only for the first 20 days after which it is equal to the monthly rent.
