C(L(x)) = 2.7800x
O C(L(x)) = 0.9180x
O C(L(x)) = 0.7803x
C(L(x)) = 0.7225x

Step-by-step explanation:

Given

----- Sales price

---- Loyalty member discount

Required

This is represented as: L(S(x))

So, we have:

Substitute S for S(x)

Substitute

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
