Answer:
£45
Step-by-step explanation:
Say the original price is x. When we take 20% off, that's basically multiplying x by 20% and then subtracting that product from the original price, which is x:
x - 20% * x = 80% * x = 0.8x
Now, this equals £36, so we just set them equal:
0.8x = 36
Dividing by 0.8 from both sides, we get:
x = £45
Thus, the answer is £45.
