Julia’s Muffin Maths
Julia, Antoine, Alvaro, and Oliver were planning recipes for a cosy bake sale. They wanted everything organised before they started mixing.
Julia said, “Let’s make two batches of blueberry muffins and one batch of banana muffins.” Antoine checked the cupboard and counted exactly 78 eggs.
Alvaro read Julia’s recipe notes: “Each blueberry batch uses x eggs. The banana batch uses 18 eggs.” Oliver added, “We’ll use every egg we have, so nothing is left over.”
Julia smiled. “Perfect. Once we know x, we can write the shopping list for next time.”
They lined up their bowls and labels, pleased that the plan was neat and tidy. Antoine tapped the recipe card. “Right then—how many eggs go into one blueberry batch?”
Alvaro picked up a pencil, ready to fill in the missing number beside the letter x, while Oliver held the egg box open so they could double-check the total.
Everything depended on that one value, and the muffins depended on them.
