Answer 8

In general, direct variation between \(y\) and \(x\) is modeled as
\(y=kx\) where \(k\) is some (fixed) constant..

Answer 9

ok

Answer 10

So, if each room is \(22\) dollars, than the cost for \(x\) rooms, \(y\), is \(22\times x\) (or \(22x\)).

Answer 11

So, if you were to set an equation for \(y\) (the cost of cleaning \(x\) rooms) ...
