On the first warm Saturday of spring, three friends set up a lemonade stand at the end of their street. They decided to sell lemonade by the cup and by the jug, but in their rush to start, they forgot to label the prices. By lunchtime, they had plenty of customers – and a very confusing notebook full of sales.
In one sale, a neighbour bought two cups and one jug for £8. Later, a family stopped by and bought one cup and two jugs for £10. At the end of the day, when they checked their records, they realised that one large order – three cups and three jugs – had brought in exactly £18.
“That can’t be right,” said Lucy. “The numbers don’t add up!”
Tom laughed. “They do if you solve for them,” he said, tapping the notebook like a detective with a clue. “We can work out how much each costs.”
