Help! "Asha needs at least 1 worker for every 30 visitors to the car show...."

Asha needs at least 1 worker for every 30 visitors to the car show.
She knows that there are going to be 550-600 visitors.

For 30 visitors Asha needs 1 worker.

For 60 ( = 2*30) visitors, Asha needs (1*2 =) 2 workers.

For 90 ( = 3*30) visitors, Asha needs (1*3 =) 3 workers.

For 600 ( = ? * 30) visitors, Asha needs (1* ? =) ? workers.

20 * 30 = 600

So she needs 20 workers?

Thank you
