Answer: 266,667 bottles
Step-by-step explanation:
- 80/300 people preferred soft drink z. This as a decimal is 0.2666
This means that out of the million, 0.2666666666666667% need to be soft drink z
1,000,000x0.2666666666666667 =266,666.667
This can be rounded to 266,667 bottles of soft drink z

4 squared + b squared = 8 squared
