Turkey has a population of $66$ million people and is made up almost entirely of two ethnic groups: Turks and Kurds. There are four times as many Turks as Kurds. How many Kurds live in Turkey?

Let $k =$ the number of Kurds in Turkey. Write an expression that represents the number of Turks ($t$).

Set up an equation that says $t + k = 66\text{,}000\text{,}000$.
