Answer:
There are 40 families in the suburb.
Step-by-step explanation:
Given that 85% of the families own a beagle.
Let x be the total number of families in the suburb.
It is also given that 34 families own a beagle
Which means that 85% of x is 34
This can be written as:
[tex]34 = 85\%\ of\ x\\34 = 0.85x\\\frac{0.85x}{0.85} = \frac{34}{0.85}\\x = 40[/tex]
Therefore, there are 40 families in the suburb.
