Given that he needs to buy some fabric for his wood shop and that each apron is 1/2 feet long and 3 feet wide, this means that the whole fabric that he needs is a total of 4.5 feet long and 27 feet wide. We cannot determine how many pieces of fabric he needs since the measurement of the fabric sold is not specified in the problem.
Answer: The domain is 
and the range is ![\boxed{[-4, 4]}](https://tex.z-dn.net/?f=%5Cboxed%7B%5B-4%2C%204%5D%7D)
.
Step-by-step explanation:
The domain is the set of x-values and the range is the set of y-values.
Speed of the boat = u
speed of the current = v
In downstream,
u - v = 280/7
u - v = 40
In upstream,
u + v = 280/14
u + v = 20
Add both equations
2u = 60
u = 30
v = -10
Speed of the boat = 30 km/h
