Dominique paid $15.50 to join an online music service. She purchases 10 songs each month at a cost of $0.99 per song. Dominique thinks that after 8 months, she will have spent around $75.00 total. Is Dominique's estimate reasonable?
To determine if Dominique's estimate is reasonable, we need to calculate the total cost of the music service subscription and the cost of the songs purchased over 8 months.
The subscription cost is a one-time payment of $15.50.
The cost of songs purchased each month is $0.99 per song, and Dominique buys 10 songs each month. So the monthly cost of songs is 10 * $0.99 = $9.90.
Over 8 months, the total cost of songs purchased would be 8 * $9.90 = $79.20.
Adding the subscription cost and the cost of songs purchased, we have $15.50 + $79.20 = $94.70.
Therefore, Dominique's estimate of spending around $75.00 is not reasonable as it is lower than the actual expected cost of $94.70.
