The answer to the first question is 30.
Answer: 
This translates to "y is any real number such that it is 0 or larger".
The reasoning is that the result of any absolute value function is either 0 or positive. In other words, we'll never get a negative result of an absolute value function. This is due to how absolute value represents distance. Negative distance does not make sense.
So if y = |x-3| then y = 0 is the smallest output possible. We could have any positive output we want.
In terms of a graph (see below), the V shape is at the lowest point (3,0). The y coordinate is all we care about in terms of finding the range. So we see the lowest y value is y = 0.

Answer:
$2147.85
Step-by-step explanation:
199.5*.5=99.75
199.5+99.75=299.25
299.25*.3=89.775
299.25-89.775=209.475
209.475*.04=8.279
209.475+8.379=217.854
