Yesterday, a local radio station played 85 songs prior to 10 a.m. The station also played 9 songs per hour for the remainder of the day. If a person listened to the radio station yesterday afternoon for x hours, which of the following equations can be used to find the number of songs the person listened to? A. y = 9x + 85 B. y = x + 9 C. y = 9x D. y = 85x + 9

OpenStudy (math&ing001):

The 85 songs don't concern us here since he only started listening in the afternoon. So the number of songs will solely depend on the number of hours he's been listening. Which do you think fits best ?

OpenStudy (rayman5766):

would be y=9x because of times hours ?

OpenStudy (math&ing001):

Yep !
