Question

Cant figure this out

Answer 1

The michine is taking away 6 from each number. If she put in 77 she would get 71

Answer 2

Since Katie entered the number 15 and it displayed 9 the machine in this case is doing whatever number you put in -6 so it displayed 9 again when 23 is entered 23-6 = 17 and that is what displayed and again for 100 and 94 so the machine is taking 6 off each time.

A, The machine is taking 6 off each time.

if you enter 77 and 6 was taken off it would be 71 so 71

B, 71
