**Reiny**, Thursday, December 1, 2011 at 5:46pmlet the number of $1 increases be n

Number of cars sold = 180-5n

rate per car = 32+n

income = (32+n)(180-5n)

= 5760 + 20n -5n^2

d(income)/dn = 20 - 10n

= 0 for a max/min of income

10n = 20

n = 2

There should be two $1 increases

they should be rented at $34 and they should rent 170 cars for an income of 170(34) or $5780
