Answer
Answer key: BOGO worksheet
Calcapedia 1. Real percent off, spread over every item: 12.5%
Add the items you buy and the items you get, to see how many you take home
Work out what all of them would cost at the regular price
With the deal, you pay full price for the items you buy, and 50% less for each extra one
Your savings are the regular total minus what you pay
Divide the savings by the regular total to get the real percent off across all the items
Divide what you pay by the number of items to get the real price of each one
For the other offer, take 50% off the regular price of all 4 items
Compare the two totals. A positive number means the multi-buy deal is cheaper
