Part a: Cost of downloading album B = 13.3 euros
Part b: Cost of downloading album B = 12.6 euros
Number of tracks in album A = 11 tracks
The total cost of downloading album A = 10.45 euro
Cost of each track on album A = Total cost of album/Number of tracks in the album
= 10.45/11
= 0.95 euro
Part a:
Number of tracks in album B = 14 tracks
Cost of album B = Number of tracks in album B * Cost of each track
= 0.95*14
= 13.3 euros
Part b:
The cost of 5 tracks on album B is 5p less therefore, the cost of 5 tracks will be 0.90*5 = 3.60 euros
The cost of 9 tracks on album B is 5p more therefore, the cost of 9 tracks will be = 1*9 = 9 euros
The total cost of downloading album B = 9+3.6 = 12.6 euros
