What is a linear equation?
"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, 'x' is a variable, 'A' is a coefficient and 'B' is constant."
Given, the percent of discount 25% = 0.25.
Sale price $40.
Let, the original price is x.
Therefore, [x - (x × 0.25)] = 40
⇒ (x - 0.25x) = 40
⇒ 0.75x = 40
⇒ x = (40/0.75)
⇒ x = 53.33
Therefore, the original price is $53.33.
