Question

An animal shelter uses 41 cups of food each day to feed the dogs and cats. Each dog eats 2 cups per day. The cats eat a total of 17 cups per day. The diagram represents this situation. Which equation can be used to find d, the number of dogs at the shelter?

Answer 1

The equation that can be used to find d is
`2d+17=41`

`d=12\ dogs`

Explanation:

Let

d -----> the number of dogs

we know that

The linear equation that represent this situation is

`2d+17=41`

Solve for d

Subtract 17 both sides

`2d=41-17`

`2d=24`

Divide by 2 both sides

`d=12\ dogs`
