Answer:
Step-by-step explanation:
Let b represent the number of beams.
Let c represent the number of connector plates.
Each aluminum piece is either a beam, which weighs 100 kg, or a connector plate, which weighs 2 kg. The total weight of b beams and c connector plates would be
100b + 2c
The boat must carry aluminum pieces for a construction project that weighs, in total, no more than 50,000 kilograms. Therefore, the equation becomes
100b + 2c ≤ 50000
