GCSE Maths Practice: forming-equations

Question 2 of 10

This question tests forming equations from percentage discounts. Understand percentages and equations.

‹ ›

\( \begin{array}{l}\text{A product is sold for £76 after a 20% discount.} \\ \text{Which equation models the original price before discount?}\end{array} \)

Choose one option:

\( 0.8x = 76 \) \( x - 0.2 = 76 \) \( x = 76 - 0.2x \) \( 0.2x = 76 \)

Convert percentage to decimal, multiply by original price, equate to discounted price.

Use the formula: discounted price = (1 - discount%) × original price.
