Final answer:
To find the original price of the trainers, we divide the sale price, £84, by 0.7, resulting in an original price of £120, corresponding to option A.
Step-by-step explanation:
To determine the original price of the trainers, we need to set up a simple equation based on the given information. The sale price of £84 is said to be 70% of the original price. If we denote the original price by 'x', then we can express this relationship as: 0.7x = £84. To find 'x', we divide the sale price by 0.7:= £84 / 0.7x = £120
Thus, the original price of the trainers was £120, which corresponds to option A.To find the original price of the trainers, we need to determine what 100% of the original price is. Since the trainers are on sale for 70% of the original price, we can set up the equation:70% of X (original price) = £84To solve for X, we can divide both sides of the equation by 70% (or 0.7). This gives us:X = £84 / 0.7 = £120Therefore, the original price of the trainers was £120. If we denote the original price by 'x', then we can express this relationship as: 0.7x = £84. To find 'x', we divide the sale price by 0.7:= £84 / 0.7x = £120
