Answer:
(C) Nathaniel can build at most 3 birdhouses.
Step-by-step explanation:
Given that:

where:
- B represents the number of birds
- H represents the number of Birdhouses
Nathaniel wants to build 50 birds(B) using lego Blocks, we want to determine how many birdhouses(H) he can build with the remaining Lego blocks.
If B=50

Therefore, Nathaniel can build at most 3 Birdhouses.
3r-6=-21
3r-6+6=-21+6 (Add 6 to both sides...)
3r=-15
r=-5
3r-6=21
3r-6+6=21+6 (Add 6 to both sides...)
3r=27
r=9
r=-5 or r=9
You just do 280 x 1.17= 327.6
