Using the percentage concept, the percentage of the regular price is 27.5%

Given tha Parameters :

  • Normal cost = $30

  • Discounted cost = $21.75

Let the percentage discount = p

We can create an expression thus :

  • Discounted cost = %discount × normal cost

21.75 = (p/100) × 30

21.75 = 0.01p × 30

0.725 = 0.01p

p = 0.725 / 0.01

p = 72.5

Hence, the percentage of the regular price is (1000% - 72.5%) = 27.5%
