Answer:

1,600 dentists were surveyed in total.

Step-by-step explanation:

We can set up a proportion for this problem:

[tex]\frac{27}{40} = \frac{1080}{x}\\\\\\[/tex]

Now we can cross multiply:

[tex]27*x = 1080*40\\\\27x = 43,200\\\\27x/27 = 43,200/27\\\\x = 1,600[/tex]

1,600 dentists were surveyed in total.
