What help do you need with this? Please show us what you have tried, so we can guide you to the next step, or correct any mistakes you have made.

If you haven't started yet, one way to start (of many) would be to define a variable x representing the number of users who use the Windows phone. Then find the weighted average number of logins per month (or is it per day??) over all users, and set that equal to 15.
