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.

<span>Starting with x−24/x<10 multiply everything by x. x^2-24<10x Subtract 10x from both sides. x^2-10x-24 < 0 Factor. (x-12)(x+2) < 0 (x+2) is always positive since x > 0, but (x-12) is negative when x is a value between 0 and 12. This negative value for (x-12) satisfies that the left side is less than 0. Thus the solution set for x is (0,12).</span>
