Hey guys. Generally, I find maths quite easy, but whilst revising for my exam in June, I came across this, and genuinely don't have a clue. Would love if someone could put my mind at rest! 1. When the price of an apple rises by 12p, I can buy ten fewer for £7.20. a) Let the price of an apple before the price rise be x pence. Show that 720/x - 720/x+12 = 10 b) Find the price of an apple before the price rise. A solution by trial and improvement will not be accepted. Would be so, so, so thankful if someone could work it out!
