Question

A hairdresser receives a discount on each comb purchased. The original price of each comb is x dollars. The hairdresser purchases 25 combs for a total of (25x-100) dollars. By how much is each comb discounted? $□?

Answer 1

$4

Explanation:

Original price of comb = x

Number of combs = 25

Amount paid after discount = (25x - 100)

From the expression :

Price of comb before discount : 25 * x

Discount on all 25 combs = 100

Discount on each comb = 100 / 25

= $4
