# Feeding Yourself on a Budget

Eating well on a fixed amount of money is a planning problem, not a willpower problem. Unit price, batch cooking, and what actually gets eaten before it spoils decide the outcome.

## Ready when they can

- Compare two package sizes by price per unit and say when the bigger one is not the better deal
- Build a week of meals to a stated spend and show the arithmetic
- Name two cheap ingredients that carry protein and say what to do with them
- Explain why food thrown away is the most expensive food in the shop

## Lesson: Feed yourself on a fixed sum

Eating well on little money is a planning problem. Compare package sizes by price per unit, like per pound or per 100 grams. The lower unit price usually wins, so do the division before you choose.

The bigger bag is not always the better deal. If food spoils before you eat it, the wasted part still cost you money. Food thrown away is the most expensive food in the shop.

**Example.** Run the numbers for a week. Rice at 1.40 per pound times 5 pounds costs 7.00. Pasta at 1.25 per pound means 5.00 buys 4 pounds. Split the week between fresh food and cupboard staples, and check the total against your fixed sum. For a sale, check the claim backwards: 40 percent off leaves 60 percent, and 60 percent of 1.50 is 0.90.

**Tip.** Lean on cheap carriers. Tinned beans bring protein to soups and stews for little money. Oats bulk out porridge and baking for little money. Plan meals around them, track spending through the week, and adjust before the money runs out.

**Recap.** Compare unit prices, plan the week, and waste nothing.
