There are 20% fewer dogs than cats. All together I have 171 dogs and cats. How many dogs do I have and how many cats do I have?

Question

I need an equation   

Answer 1

Let number of cats = x

Let number of dogs = x - 0.20x = 0.80x

 

Using these variables, write an equation that shows the total amount of dogs.

 

x + 0.80x = 171

 

 

Solve the equation for x.

 

1.80x = 171

 

 

Divide both sides of the equation by 1.80

 

x = 95

 

 

There are 95 cats and 76 dogs.
