Making Change and Checking a Receipt
Aligned to JS:FD-2 — Jump$tart National Standards in K-12 Personal Finance Education & Advance CTE Career Clusters.

What this lesson teaches
Paying with cash means getting change back, and the person handing it to you can make a mistake. Counting up from the price to the amount you paid is the fastest way to check. The receipt is the record of what you were actually charged.
Worked examples
Example 1
A snack costs $6.35 and you pay with a $10 bill. Count up: 65 cents to $7, then $3 to $10 — so your change is $3.65.
Example 2
Check the receipt against the shelf price. An item rung up at the regular price when it was marked on sale is a common and fixable error.
Example 3
Keep the receipt until you are sure you are keeping the item. Most stores will not take a return without it.
Practice questions
- An item is $12.40 and you pay $20. What is your change? Count up.
- Look at a real receipt and find the subtotal, the tax, and the total.
- Why should you keep a receipt after you leave the store?

Dar cambio y revisar un recibo
Pagar en efectivo significa recibir cambio, y la persona que te lo da puede equivocarse. Contar hacia arriba desde el precio hasta lo que pagaste es la forma más rápida de revisar. El recibo es el registro de lo que realmente te cobraron.
Ejemplo 1: Un bocadillo cuesta $6.35 y pagas con un billete de $10. Cuenta hacia arriba: 65 centavos para llegar a $7, luego $3 para llegar a $10 — tu cambio es $3.65.
Ejemplo 2: Compara el recibo con el precio del estante. Que te cobren el precio normal cuando estaba marcado en oferta es un error común y se puede corregir.
Ejemplo 3: Guarda el recibo hasta estar seguro de que te quedas con el artículo. Casi ninguna tienda acepta una devolución sin él.
