3) D

We can eliminate option C because Chestnuts’ cost is $900,000 which is more than the family’s budget.

Bellavista and Everglade only satisfy 3 out of the 5 wishes. So B is wrong

Acorns fulfils 4 wishes.

Cost per bedroom = $825,000 / 5 = $165,00

Dayview fulfils 4 wishes.

Cost per bedroom = $640,000 / 5 = $160,000

Since Dayview fulfils 4 wishes and has the cheapest cost per bedroom, D is the answer.
