The answer is b because 7 plus 2 equals 9 and a equals whole amount then his current amount is A-9
Answer:
C
Step-by-step explanation:
- Following the order of operations, we do parenthesis first.
- Multiply out the value against the parenthesis.
- This leaves us with 20 over 20. 20 goes into 20 only 1 time, so our final answer is 1.
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
