Explanation / Answer

Answer

Parents will pay upto $250 so the child can either choose to stay in a three bedroom flat as it will cost

750$/3 = $250 ( Exactly the amount) or four bedroom that will be $900/4 = $225. As these amounts lie in the budget that was upto $250.

OPTION C & D.

2. Now suppose we choose four bedroom flat with cable that will be 4 - $900+$60 + $960

and this whole amount will be divided by four.

Therefore , 960/4 = 240 $

The average fixed cost per roomate will be $240.

3. The total cost associated with four bedroom flat as calculated above is $960 ($900+$60).

Now rather than sharing amond four only three people are sharing that room. So, $960/3 = $320.

The average fixed cost per roomate will be $320 if only three people are sharing that room.

Excluding the cable the rent was $900 which is being divided among three - $900/3 = $300

And as parents are paying $250. Thus he need to pay 300-250 = $50 on his own.
