8/2 is 4 and -10 + -2 is -12 because your adding two negatives
The answer is 14% because that's the amount between 20 and 34 and your trying to find the percent between those two
You most likely have to multiply 10 (7 times) and whatever your answer is then you multiply your answer times 64
On the 14 week Juan will save $ 52 because each 3 week he earns 3.
So you do 9 divide by 3 and get 3. Then you do 3 times 2 and get 6.
46 + 6 = 52
