Question

Two friends decide to rent an apartment and split the cost evenly. They each paid $575 towards the total move in cost of first and last month's rent and a security deposit. If the apartment cost $325 per month to rent, how much was the security deposit?

Answer 1

The total amount paid by the friends equals to :

575 × 2 = 1150

= $ 1150

This is inclusive of the first and last month rent and a security deposit.

The monthly rent is $ 325

For the two months it will be :

325 × 2 = $ 650

1150 - 650 = 500

the security deposit is thus :

$ 500
