What is the cost for the beams and channels?
Once you know what beams cost fill them in this equation as “b” and channels as “c”:
3b+6c<75
If this is true, the grant will cover the cost. If this is false, the grant will not cover the cost.
Hope this helps! You can comment if you still have a hard time and I’ll try to help. Pls mark brainliest if it helps.
