Question

using complements (with respect to 1) of the single discounts, find the net cost equivalent for the discount 30/10/5. the net cost equivalent is \boxed{}

Explanation:

Step1: Find complement of 30% discount

A 30% discount means we pay \(1 - 0.30 = 0.70\) of the original price.

Step2: Find complement of 10% discount

A 10% discount means we pay \(1 - 0.10 = 0.90\) of the price after the first discount.

Step3: Find complement of 5% discount

A 5% discount means we pay \(1 - 0.05 = 0.95\) of the price after the second discount.

Step4: Calculate net cost equivalent

Multiply the three complements together: \(0.70\times0.90\times0.95\)
First, \(0.70\times0.90 = 0.63\)
Then, \(0.63\times0.95 = 0.5985\)

Answer:

\(0.5985\)
