iTunes would have an equation that looks like y=1.29x, Spotify would have an equation that looks like y=9.99, and soundwaves would have an equation that looks like y=0.75x+2.99 if we look at the price of music subscriptions for 1 month. By graphing or solving this system of equations using substitution or elimination If students download less than 6 songs a month iTunes purchases is the best choice If students download 6-9 songs a month SoundWaves will be the best choice. If students download more than 9 songs a month Spotify Premium will be the best choice.
