Percent in money: discounts, profit and loss

Use a 100% bar to see how much a discount takes off a price, and what percentage of the cost a seller gains or loses.

Guide

In each problem the whole bar is 100%: the original price or the cost. With 10 parts each part is 10%; with 4 parts, 25%; with 5 parts, 20%.

A discount is the amount taken off the price. 20% off means you pay 80% of the price.

A seller buys something (the cost) and sells it. Selling for more makes a profit; selling for less makes a loss. The percentage profit or loss is always worked out from the cost.

This is not in the Key Stage 2 curriculum: it is extra, for when you are ready (Key Stage 3).
