Math Is Fun Forum

Hi guys

I recently moved to australia and here the rentals are taken per week rather than per month
I had enquired with a guy who had advertised his flat at AUD 200 per week
Here we can have a tenancy of fixed period like 3 months, so that person send me below calculation of the rent he's going to charge me

Below is what he wrote

------------------------------------------------------------
Rent per week = AUD 200
Annual rent = Weekly rent  x 52

$200 x 52 = $10,400
Monthly rent payment = Annual rent/months per year
$10,400/12 = 866.67
If a tenant makes 12 payments of $866.67 the total rent is $10,400 This is the same as 52 payments of $200.

------------------------------------

Now what my expectation is rent per week is $200  but by above calculation he is expecting rent of --- 866.67 monthly - rent per week = $ 216

I know he's trying to confuse and fool me in figures what what's the logic in his calculation
Kindly suggest as I want to give him a befitting reply

Thanks
