Answer 1

Answer:

The option C) 0.14N is correct

Step-by-step explanation:

Given that "A recent survey reveals that 40% of young people between 15 and 25 years of age will buy an iPod this year. If N is the number of young people between 15 and 25"

To find how many people between 15 and 25 this year will enjoy listening to country music on their iPods:

From the given we can write

Total people between 15 and 25 age = N

Number of people who buys iPods is 40% of  N is

$= \frac{40}{100}\times N$

= 0.4N

∴ Number of people who buys iPods is 40% of  N is 0.4N

From the given we have that 35 % are enjoy  listening to Country music means  

$= \frac{35}{100}\times 0.4N$

$=0.35\times 0.4N$

= 0.14N

∴  35 % are enjoy  listening to Country music is 0.14N

Hence option C) 0.14N is correct.
