$20 original = $5 final paid as $15 was s/p before -10 was added
$30 original = $14 final price as $24 was s/p before -10 was added
$60 original = $35 final price as $45 was s/p before -10 was added
$92 original = $69 final price as $59 was s/p before -10 was added

Ans in bold
A) = f(x) = 20(0.75) -10 = 15 - 10 = $5 = £5 final paid
B)= f(x) 30 (0.75) = 24 - 10 = 14 = $30 original price
C) = f(x) = 60(0.75) -10 = 45 -10 = $35 = $35 final price
D) = f(x) = 92 (75) = 69 -10 = $59 = $92 original price
