I would use a proportion for the Fred's Fouls part. Use the closest point to 12 possible, which is (15, 69.5).
Set up the proportion like so:
15/69.5 = 12/x
Now cross multiply.
15x = 834
Now divide both sides by 15 to get x by itself.
x = 55.6
Fred's Fouls will charge $55.60 for 12 wings.
Now plug in 12 as x for the Carlie's Chicken part and solve for f(12).
f(12) = 3.75(12) +10
f(12) = 45 +10
f(12) = 55
Carlie's Chicken will charge $55 for 12 wings.
Answer:
B
Step-by-step explanation:
Multiplying something by 10^-1 is just dividing it by 10.
So 3.02 / 10 = 0.302 since the decimal point moves one to the left.

Answer:
We use both median and mean to give us a sense of what the 'average' or middle of a group looks like. It may be the case that the median and mean of a given set of data are very similar. Take the data set above, for example. ... When values are evenly distributed, the mean will be similar to the median
