(Mildred) dis(cove)red (FIVE) red setter puppies in the store "(Doggies R Us)" Mildred ordered 5 (red) embroidered collars for (each) puppy at a reduced price of (�55). (Mildred's brother) Edward built 5 red (Marvel)lous kennels to shade the puppies from the red (hot sun).
But you haven't taken into account the words in brackets, each letter is a red, so Mildred would be 7, well 8 with the word red, five would be four for the letters, plus 5 'cos it's the number 5,and you could add another 5 for the roman V. �55 is red so that's three plus you could add on the 55 - the total anwer must be in the hundreds.
There was a puzzle like this on "Quiz Call" a few days ago. Somebody gave "the right answer" - it was a four-figure sum - but no explanation was offered.
