A market research company surveyed 2500 teenage cell phone owners. The company learned that 4/5 of them use cell phone data services. How many teenagers surveyed use cell phone data services?
4/5 * 2500 = 2,000
To find out how many teenagers surveyed use cell phone data services, you can use the information provided in the question.
The question states that 4/5 (or 80%) of the surveyed teenagers use cell phone data services.
To calculate the number of teenagers who use cell phone data services, multiply the total number of surveyed teenagers by the percentage who use data services:
Number of teenagers using data services = Total number of surveyed teenagers * Percentage using data services
Number of teenagers using data services = 2500 * 80/100
Simplifying the calculation:
Number of teenagers using data services = 2500 * 0.8
Number of teenagers using data services = 2000
Therefore, 2000 teenagers surveyed use cell phone data services.
