To calculate the cost of the app for \( m \) months, we need to consider both the joining fee and the monthly subscription cost.
1. The joining fee is a one-time cost of $2.
2. The monthly subscription cost is $5, and since it is for \( m \) months, we multiply this cost by \( m \).
The total cost \( c \) can thus be expressed as:
\[
c = 2 + 5m
\]
So the correct expression that represents the cost of the app for \( m \) months is:
**D) 2 + 5m**.
