= £75.00([1 - 0.3][1 - 0.1])
= £75.00(0.7[0.9])
= £75.00(0.63)
= £47.25
Answer: £47.25 is the jacket now.
Checking:
= £75.00 - 0.3(£75.00)
= £75.00 - £22.50
= £52.50
= £52.50 - 0.1(£52.50)
= £52.50 - £5.25
= £47.25

Just sale rack (30% off):
£75 * (1 - 0.3) = £52.5
Sale rack discount plus student discount (40% off):
£75 * (1 - 0.3 - 0.1) = £45

£75. 10% = 7.50
7.5 x 3 = 22.50
75-22.50 = 52.50
75-30 = 45
without student discount: £52.50
WITH student discount: £45
aha i'm happy now, my GCSE is next month and i could do that really easily :)
