The correct answer is 8.96.
To find the total cost for x songs, we can use the equation:
f(x) = 0.99x + 5
Plugging in x=4:
f(4) = 0.99(4) + 5
f(4) = 3.96 + 5
f(4) = 8.96
Therefore, the total cost for 4 songs would be $8.96.
To evaluate f(4) for the function of total cost for x songs, we need to find the total cost for 4 songs using the given information.
First, we know that there is a $5 fee to become a member. This fee is paid regardless of the number of songs downloaded. So, the initial cost is $5.
Next, we need to calculate the cost of the songs. Each song costs $0.99, and we want to find the cost for 4 songs. Therefore, we can multiply the cost per song by the number of songs: 4 * $0.99 = $3.96.
Finally, we add the initial cost to the cost of the songs to get the total cost: $5 + $3.96 = $8.96.
Therefore, f(4) is equal to $8.96.
To evaluate f(4), we need to find the total cost for downloading 4 songs.
Given that the company charges $0.99 per song and a $5 fee to be a member, the total cost can be calculated as:
Total cost = (Number of songs * Cost per song) + Membership fee
Plugging in the values, we have:
Total cost = (4 * $0.99) + $5
Total cost = $3.96 + $5
Total cost = $8.96
Therefore, f(4) = $8.96.
The correct answer is 8.96.
