A new app charges a joining fee of $2 and a monthly subscription cost of $5 each month. Choose the expression below that represents the cost of the app for m months?

Question

A) 5 + 2m
B) 2 + 5 = c
C) 5 + 2m = c
D) 2 + 5m

Answer 1

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.
