Answer:
The 2nd case is the better value
Step-by-step explanation:
£11.45
Case 1: That would be £11.45 + -------------- for the two shirts. This comes
2
out to 1.5(£11.45) = £17.175 for two shirts.
Case 2: Two shirts for £10.16 each comes out to £20.32; multiplying that by (1.00 - 0.20), or (0.80) results in (0.80)(£20.32) = £16.256.
The 2nd case is the better value, as one would get 2 shirts for £16.26, versus 2 shirts for £17.18 in the other case.
