Farmers

Farmers loaded into a truck of fruit and vegetables intended for the store. 10 boxes of 5 kg pears, 8 boxes of 6 kg plums, 7 boxes 9 kg of carrots, and 10 bags of 50 kg of potatoes. How many kilograms of fruit and vegetables are loaded in total? How many kg could still be loaded if the car can carry up to one ton of goods?

Correct answer:

a =  661 kg
b =  339 kg

Step-by-step explanation:

$a=10\cdot 5+8\cdot 6+7\cdot 9+10\cdot 50=661\text{kg}$

$b=1000-a=339\text{kg}$
