Andrea, paid $9.99 to join an online music service if she purchases 12 songs each month at a cost of $.80 per songs what will be the total spent after six months
First, let's calculate the total cost of purchasing 12 songs each month at a cost of $0.80 per song:
12 songs * $0.80 per song = $9.60 per month
After 6 months, the total spent on songs will be:
$9.60 per month * 6 months = $57.60
Adding the initial cost of joining the online music service:
$57.60 (total spent on songs) + $9.99 (initial membership fee) = $67.59
Therefore, Andrea will spend a total of $67.59 after six months of purchasing 12 songs each month at a cost of $0.80 per song.
