Answer provided by our tutors
let x = the number of rooms cleaned, x is integer
The Great Maids cleaning service will charge: 50x + 185
The Spic-n-span cleaning service will charge: 65x
The Great Maids cleaning service is a better service then Spic-n-span cleaning service means:
50x + 185 < 65x
by solving we find
x > 12.33
