Question

Dimtry bought a pair of pants at the discounted price of $30. The original price of the pants was $40. What was the percent of the discount?

PLEASE EXPLAIN TO ME HOW YOU GOT YOUR ANSWER

Answer 1

The discounted price and the percentage are equal to the original price:
30+(40*x/100) = 40
40*x/100=10
40x=1000
x=25% of the discount
