The answer is A 0,8*1,25 = 1 1 = 100 % 0,8 = 80 % the discount is 20 %

(-1,1) is right -1 on the x-axis and 1 on the y-axis.

For me it´s C - 20. 16/4=4 20/4=5 5*4=20

It must be C because the median is the middle one! Therefore one house must be below!

Isr, that is right but why? 2^34 - 2^28 = 2^6 2^6 = 64! Why -1? Thanks
