Question

Harry downloads album A which has 11 tracks.

Answer 1

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
