Goods are things, such as bread. Services are work done for others, such as a haircut. Producers make goods or provide services. Consumers buy and use them. Buying is one part of the economy, as you learned in the shop lesson. **Example.** Mia's uncle grows strawberries to sell. He is a producer of strawberries. Mia's family buys and eats them, so they are consumers. Her uncle buys bread for his lunch. In that purchase, he is a consumer too. One person can be a producer in one trade and a consumer in another. Demand describes how much buyers are willing and able to buy at different prices. Supply describes how much sellers are willing and able to offer at different prices. Wanting an item without being able to pay is not enough. Cones cost $2 on both days. On the hot day, eight buyers each want and can pay for one cone. If the shop offers six cones, two requests cannot be met. The cold day has two buyers. When demand rises but supply stays the same, prices tend to rise. When demand falls, prices may fall. More supply with unchanged demand tends to lower prices; less supply tends to raise them. A delayed delivery can reduce supply. These are tendencies, not promises. Sellers may keep a posted price unchanged. *(drawing: A delivery adds six baskets. The price is $3 per basket before and after the delivery.)* Compare amounts at the same price. More wanted than offered is a shortage. More offered than wanted is a surplus. Matching amounts are a balance, called equilibrium in a market model. Find a missing amount by subtracting what is offered from what is wanted. Nine buyers each want and can buy one basket, but six are offered: 9 - 6 = 3 baskets missing. A price change also affects buying. If other things, such as income and tastes, stay the same, a higher price usually means a smaller quantity demanded. A lower price usually means a larger quantity demanded. This is the law of demand. A price cut alone does not show that shoppers' tastes changed. **Recap.** Producers offer goods and services; consumers buy and use them. Supply and demand affect prices, but prices do not always change at once. *Lesson, questions and flashcards written for this dataset.* ## Practice 14 questions on this page, each with its working shown. ## Needs first - [Jobs People Do](https://lightmysky.com/learn/life-skills/jobs-people-do-mt_asRwlPZXC3) - [Buying things](https://lightmysky.com/learn/life-skills/buying-things-mt_RNRymbz5SO) ## Optional connections - [Advertising & Spending](https://lightmysky.com/learn/life-skills/advertising-and-spending-mt_My0OL6fhGL) ## Opens up - [Global Trade](https://lightmysky.com/learn/life-skills/global-trade-mt_0Rx1ISxXFE) - [Taxes & Public Services](https://lightmysky.com/learn/life-skills/taxes-and-public-services-mt_cSz7XTxVAx) - [Externalities and Spillovers](https://lightmysky.com/learn/civics-and-economics/externalities-and-spillovers-mt_F4SQsGpZk9) - [How markets work](https://lightmysky.com/learn/civics-and-economics/how-markets-work-mt_IWiQW8Sq2R)
