Answer:
To solve this problem, we can use the following equation:
original price - (40% x original price) = £750
We know that the original price decreased by 40%, which means that the new price is equal to 60% of the original price. So we can rewrite the equation as:
original price x 0.6 = £750
To solve for the original price, we can divide both sides by 0.6:
original price = £750 ÷ 0.6
original price = £1250
Therefore, the original price of the car was £1250 before the 40% decrease in price.
