Answer:

The total cost of the cleaning service is $180

Step-by-step explanation:

We have, 30% × x = 54

or,

30/100 × x = 54

Multiplying both sides by 100 and dividing both sides by 30,

we have x = 54 × 100/30

x = 180

If you are using a calculator, simply enter 54×100÷30, which will give you the answer.
