I came to the vegetable market and wanted to buy food. The food in the market 1.5 yuan, ready to buy 2 kg. But I looked at the food outside the market, which is 1.2 yuan, which is more delicious than the food inside. I was going to buy another catty and fry it at night, which not only bought more vegetables, but also became cheaper and cheaper.

Then, I go to buy meat. The meat in the market is lean, 4.5 yuan is a catty. As for the meat outside the market, 4.5 yuan needs a catty of lean meat. In contrast, I certainly choose meat from the market. So I bought 3 Jin of meat and spent 4.5×3= 13.5 yuan.

Then, I went to buy chicken legs. It is harmful to flies to see that chicken legs on the market have less meat and more bones. I asked for a kilo of 6 yuan. I looked at the chicken legs outside the market again. I saw it was meaty and bony, delicious and pollution-free, but it was a little expensive, 8 yuan a catty. However, for the sake of health, it is more expensive! And it's only 8-6=2 yuan, so I bought a kilo.

With the delicacy of crucian carp, I came to a crucian carp stall. The crucian carp here is fresh and tender, and it is the first-class crucian carp. Crucian carp in other stalls are not so good. But the crucian carp here is too expensive, 10 yuan a kilo. So I bargained with the stall owner's aunt and said, "Aunt, the crucian carp you have here is very good, but it is too expensive." Aunt said, "you know this fish is good, little friend." To 10 yuan is already very cheap. " I talked with my aunt for a long time, and she agreed, but it was only one yuan cheaper. I looked at the money in my pocket, only 4.9 yuan was left. So I had to buy half a catty of flowers (10).

On the way home, I counted the dishes and figured out that I used 3.6+ 13.5+8+4.5=29.6 (yuan) for a * *, plus 29.6+(4.9-4.5)=29.6+0.4=30 (yuan) for the rest.

I was deeply impressed by buying vegetables this time.
