45 people is 10% of 450.
So how many people is 30% of 450. 

1. Multiply (45)(3) = 135. Because 30% is 3 times 10%. 
2. Multiply (450)(.3) = 135. Because .3 = 30% in decimal form.

vazorg [7]

Answer:

there are 12 dogs.

Step-by-step explanation:

d= dogs              now plug in the 4 into your equation.

d+c=16                   d=12

3c+c=16

4c=16                        SO THEREFORE THERE ARE 12 DOGS :)

c=4
