Worked Solution & Mark Scheme (4 marks)
Part (a) Solution:
As the number of downloads increases, the number of CDs sold increases
Answer (a): As the number of downloads increases, the number of CDs sold increases
Part (b) Solution:
From the line of best fit at 9000 downloads, number of CDs sold = 5500 M1
Earnings from downloads = 9000 × £2.50 = £22 500 M1
Earnings from CDs = 5500 × £3 = £16 500
Total = £22 500 + £16 500 = £39 000 A1
Earnings from downloads = 9000 × £2.50 = £22 500 M1
Earnings from CDs = 5500 × £3 = £16 500
Total = £22 500 + £16 500 = £39 000 A1
Answer (b): Answer £ 39 000
