Each birdhouse uses 12 sq ft of wood.
He has enough to build 10 birdhouses, so he has 120 sq ft of wood.
The function has an input of the number of birdhouses, b, and has an output of the amount of wood needed, W. b is the input or the domain, and W is the output or the range. The domain is 0 to 10. The range is 0 to 120.
Answer: B. D: 0 ≤ b ≤ 10 R: 0 ≤ W(b) ≤ 120

Answer:
x = 166,152
Step-by-step explanation:
x = 3.491
y = 7.342
x =?
y = 349,439
therefore,
3.491/x = 7.342/349439
1,219,891.549 = 7.34x
divide through 7.34 and make subject
x = 166,152
