Answer:
In this case, they are using a simple random sampling method, because in each store they choose 100 random people without stratifying them or put any condition. In the simple random sampling method, the samples have the same probability to be chosen, but it isn't reliable in big populations. The population is all the costumers that visit all the stores, while the sample is just the costumers that were surveyed in all the stores. So, it's a simple random sampling method, and the population is all the people that visit all the stores.
The answer is: x = 400
Here's how I got my answer:
Step 1: Subtract .60 from both sides. Leave us with ![100=20+0.80x-0.60x](https://tex.z-dn.net/?f=%20100%3D20%2B0.80x-0.60x%20)
Step 2: Simplify
to
. Which leaves us with ![100 = 20 + 0.2x](https://tex.z-dn.net/?f=%20100%20%3D%2020%20%2B%200.2x%20)
Step 3: Subtract 20 from both sides. Which leaves us with ![100-20=0.2x](https://tex.z-dn.net/?f=%20100-20%3D0.2x%20)
Step 4: Simplify
to 80. Which leaves us with ![80 = 0.2x](https://tex.z-dn.net/?f=%2080%20%3D%200.2x%20)
Step 5: Divide both sides by 0.2. Which leaves us with ![80/0.2 = x](https://tex.z-dn.net/?f=%2080%2F0.2%20%3D%20x%20)
Step 6: Simplify
to 400. Which leaves us with our answer, x = 400
