Question

You and your sister decide to adopt a dog. When buyingdog food, you notice that the recommendation is a cup ofdog food a day for every 10 pounds that the dog weighs. Ifyour dog weighs 50 pounds, how much dog food would youfeed your dog each day?

Answer 1

So, we have an rule of three exercise:

`\frac{\text{1 cup of dog food}}{10\text{ pounds}}=\frac{x}{50\text{ pounds}}`

Now, we need to clear "x" in the ecuation:

`(1)/(10)\cdot50=x`
`x=(50)/(10)=5`

The amount you should feed your dog each day is: 5 cups of dog food.
