Answer:
A
Step-by-step explanation:
The first thing to notice is the question says it is given that the person is between the ages 23 and 60, so we only care about those people. So then we want to know how likely it would be to pick someone with over 50 messages a month. So what you would do is take the amount of people who are between 23 and 60 and send over 50 text messages, and divide that by the total amount of people 23-60 (since that is the pool of people we have). Doing so we find there is 229 people aged 23-60 which then makes the answer 157/229 or A.

Step-by-step explanation:
the problem is basically saying what 9x38 is, its just worded weird.

if you want to check, 342 is 9 times more than 38 because if you divide it by 9 u get 38
342/9=38
