At the local sweet shop, three particularly nice sweets are on special offer. A Sparkle, a Wibbler and a Nobbler together cost 40p. - A Nobbler is over three times the price of a Sparkle. - Six Sparkles are worth more than a Wibbler. - A Nobbler, plus two Sparkles costs less than a Wibbler. Can you determine the price of each type of sweet?
