Answer:
The required equation is
Charges = $(22 * No of Rooms cleaned)
Step-by-step explanation:
Direct Relation:
The relation ship in which if one quantity increase then it results in the increase of the other quantity too and if it decreases then other quantity will decrease too.
it is represented by
a∝b
a= kb
where k is constant of proportionality
Now for the given question
Charges is directly proportional to no of rooms cleaned
It is
Charges ∝ No of rooms cleaned
It could be written as
Charges = K * No of rooms cleaned
Here k is given as $22 for each room
so
it becomes
Charges = $(22 * No of Rooms cleaned)
which is the relationship in form of equation!!!
