#### Answer

Constant

#### Work Step by Step

In order to determine if a rate is constant, divide the change in the dependent variable by the change in the independent variable between every two points and see if they are the same. For every increase in the number of hot dogs by one, the number of buns always increases by one, so the rate is constant. We divide the change in the dependent variable by the change in the independent variable to find a rate of one hot dog per one bun. This means that for every hot dog we have, we need one bun.
