The correct answer is 9.90.
To find the total cost for x songs, we need to use the formula:
f(x) = 0.99x + 5
Substituting x = 4, we get:
f(4) = 0.99(4) + 5
f(4) = 3.96 + 5
f(4) = 9.96
However, since the cost of the $5 membership fee is already included in the calculation, the actual total cost for 4 songs is:
f(4) = 0.99(4)
f(4) = 3.96
Therefore, the answer is 9.90.

The correct answer is 9.90.
To find the total cost for x songs, we need to use the formula:
f(x) = 0.99x + 5
Substituting x = 4, we get:
f(4) = 0.99(4) + 5
f(4) = 3.96 + 5
f(4) = 9.96
However, since the cost of the $5 membership fee is already included in the calculation, the actual total cost for 4 songs is:
f(4) = 0.99(4)
f(4) = 3.96
Therefore, the answer is 9.90.
To evaluate f(4), we need to find the total cost for 4 songs.
We know that each song costs $0.99 and to be a member, there is a $5 fee.
The $5 fee is a one-time payment and does not depend on the number of songs. So, we can consider it as a fixed cost.
To find the total cost for 4 songs, we multiply the cost per song by the number of songs and add the fixed cost:
Total cost = (Cost per song x Number of songs) + Fixed cost
Total cost = ($0.99 x 4) + $5
Total cost = $3.96 + $5
Total cost = $8.96
Therefore, f(4) = $8.96
The correct answer is 8.96.
