Answer:
16 students got an A
Step-by-step explanation:
Set up an equation to compare the ratio to the scores:

Cross multiply:
80 = 5x
Divide each side by 5:
x = 16
Now, check if 
16/8 = 2
40/8 = 5
The ratios are the same! Therefore, 16 students got an A!

Answer: Domain: 0,1,2,3 and 4 and Range: 1,2,4,8 and 4
Step-by-step explanation:
The domain is the set of all inputs that makes the function definable. As we see the function looks like an exponential function which means the domain is all real numbers.
So the inputs are 0,1,2,3 and 4
the outputs are 1,2,4,8 and 4
The answer is the third one (C?) because if you started at 0, you are going below it since you are losing yards, causing you to have less and less yards. Adding two negatives gives you a lesser amount.
