**Reiny**, Thursday, August 8, 2013 at 8:42pmlet the number of $8 increments be n

so number occupied = 100-n

cost per unit = 416+8n

Revenue = R = (100-n)(416+8n)

= 41600+ 800n - 416n - 8n^

= 41600 + 384n - 8n^2

dR/dn = 384 - 16n = 0 for a max of R

16n = 384

n = 24

so the rent should be 416+8(24) = $608

with 100 - 24 or 76 units rented for a max

revenue of 76(608) or $46208

The answer is correct for the max profit, but it asked for the rental cost to obtain that , which

was $608 per unit.

for a max revenue of

41600 + 384(24) - 8(24)^2 or $
