Final answer:
Petra bought a wardrobe for £27 and sold it for 4/9 more than the original value, which is £12 more. She sold it for £39 in total.
Step-by-step explanation:
Petra bought a wooden wardrobe for £27 and sold it for 4/9 more than its original value. To find out how much she sold it for, we need to first calculate 4/9 of £27 and then add this to the original price.
Calculating 4/9 of £27:
£27 × (4/9) = £12
Adding this to the original price:
£27 + £12 = £39
Therefore, Petra sold the painted wardrobe for £39.
