There are 2,300 licensed dogs in clarkson. a random sample of 50 of the dogs in clarkson shows that 8 have id microchips implanted. how many dogs in clarkson are likely to have id microchips implanted

Set up a ratio comparing the sample portion to the whole portion.

x= # of all dogs likely to have chip

Sample: 8 out of 50
Whole: x out of 2,300

8/50= x/2300
cross multiply

(50*x)= (8*2300)
50x= 18400

divide both sides by 50
x= 368

ANSWER: 368 dogs in Clarkson are likely to have a microchip.

Hope this helps! :)
