Discount math diary
Mom and grandparents go shopping for new year's goods together. Get up early in the morning, drive to the farmer's market at 5: 30 and get home at 9: 30.

15 Jin of vegetables, 6 Jin of radishes, 10 Jin of spring bamboo shoots, 15 Jin of winter bamboo shoots, 5 Jin of celery and 5 Jin of potatoes were all moved back from the farmers' market in one car.

After returning home, I made an "interview" with my grandfather. I wrote down the different unit prices of each dish in the farmers' market and the food market and worked out the total price. I really want to know how much cheaper it is for my mother to work so hard.

I began to calculate:

Cheap money in farmers' market (yuan)

Unit Price/Yuan Quantity (Jin) Total Price (Yuan) Unit Price/Yuan Quantity (Jin) Total Price (Yuan)

"Ha ha! This trip is cheap 145 yuan ... Oh, great! I have to deduct the gas fee ... "Just when I was thinking about how much money I made this time, my mother said," Son, you may have to pay a fine of one or two hundred for speeding on the road. " "Ah?" I shouted: "This money is not enough!"

Hey, if it's really speeding, we really have to pay back some money! It seems that this account is not clear.
