6 0

Answer:

B

Step-by-step explanation:

First, we have to find the rate of change for this problem. To do this, we subtract any two numbers of days and the coordinating two total questions. Let's just use the first two rows. 8-4=4, and 40-20=20. For every 4 days, he answers 20 questions. We can further simplify this by dividing both sides by 4. 4/4=1, and 20/4=5. For every 1 day, he answers 5 questions. Now, to find 16 days, we just multiply both sides by 16. 16*1=16 and 16*5=80. For every 16 days, he answers 80 questions. 80 is our answer.

Hope this helps!

A father is 60 years old just son is half his age how old was the boy when his father was four times his age
gayaneshka [121]

So, what you would have to do is figure out how old he is not which is 30 yrs old because it is half of 60.

So, after this you would have to find a number that would go into 60 four times which is 15.

So, your answer would be 15.
