# Problem 7.2 (7 points)

There are 22 kg of blueberries in a box. How can you measure out 17 kg of blueberries using a two-kilogram weight and a balance scale in two weighings.
# Solution:

Place the weight on one pan and balance the scales using all the blueberries $12=10+2$, then divide the 10 kg into equal parts of 5 kg each. And we get $12+5=17$ kg.
