Campus Trade Festival Our school's annual campus trade festival has begun again. After lunch, everyone is decorating items on the playground.

Our class is no exception. There are 5 stalls arranged in one day: some sell stationery, some sell toys, and some sell trinkets.

Looking around, the playground has become a large supermarket, and the store names are also "weird": Burger Grocery Store, Boys' Canteen, Sunshine Shopping Mall, Wonderful Stall... It looks very attractive!

The trade festival has begun, and the small businessmen are busy selling their goods. The students who come to shop are always trying to bargain, which makes it difficult for the small businessmen to make a decision.

"How much is this?" the shopping classmate asked, pointing to a SpongeBob SquarePants.

I replied: "Three yuan." The classmate bargained, and I was finally convinced by her, and finally gave her the price of two yuan.

Our group is the most popular, that’s because the things we group are very practical!

Model airplanes are a favorite among boys, and cartoon hand towels are a favorite among teachers.

A model airplane costs six yuan, and a cartoon hand towel costs three yuan.

Look, our group is very popular, isn’t it?

Huh?

Amidst the shouts, I vaguely heard the sensitive words "Where are we going, Dad?", oh, it turned out to be a strange trick from the class 4 (3) classmate next door: if you buy more than 5 yuan, you will get a "Where are we going, Dad" ID card as a gift.
