How much profit does Ryan make?

£312

Step-by-step explanation:

Amount spent on 60 jumpers = £120

80% of the jumpers :

0.8 * 60 = 48 jumpers

Sales price for 80% = £8 each

Total = £8 * 48 = £384

The remain at an half price offer :

Half price = £8 / 2 = £4

£4 * (60 - 48)

£4 * 12 = £48

Total sales revenue = £(48 + 384) = £432

Total profit made :

Total sales revenue - purchase price

£432 - £120

= £312
