Question

The cost to listen to a music-streaming service is $0.99 for the first song and $0.10 for each additional song. How much does it cost to listen to 150 songs?

Answer 1

The cost for 1 song is $0.99, then from the 150 songs 149 will cost $0.10, therefore, the total cost for the 150 songs is:

`0.99+149*0.10=0.99+14.9=15.89.`

Answer: $15.89.
