A software company is developing a new app that requires users to purchase a subscription for access. The company offers three subscription plans: monthly ($10/month), quarterly ($25/quarter), and annual ($80/year). Based on market research, they expect 60% of users to choose the monthly plan, 30% to choose the quarterly plan, and 10% to choose the annual plan. Calculate the average revenue per user over one year, taking into account the different subscription plans.

To calculate the average revenue per user over one year, we first need to find out how much each subscription plan generates in a year.

1. Monthly Plan: $10/month * 12 months = $120/year
2. Quarterly Plan: $25/quarter * 4 quarters = $100/year
3. Annual Plan: $80/year

Now, let's take into account the percentage of users for each plan and multiply it by the annual revenue generated by that plan:

1. Monthly Plan: 60% * $120/year = $72/year
2. Quarterly Plan: 30% * $100/year = $30/year
3. Annual Plan: 10% * $80/year = $8/year

Finally, add up the revenues from all three plans to get the average revenue per user over one year:

$72/year + $30/year + $8/year = $110/year
