Question

Sheila is building a model for class. It's a tower that's designed to withstand high winds. She can use a maximum of 700 support beams and knows that each floor will require 22 beams. Sheila will track the number of beams that remain as she adds floors.
She can predict the number of beams that remain by using this function: remaining beams (y) is function of floor number (x).
How many beams will remain after she built 6 floors? Y=700-22(x)

Answer 1

700-132, which is 578 beams remaining.

Answer 2

Well.... 22 beams per floor. so 22(6) = 132
then, after having 700 beams, she used 12, so: 700 - 132 = 568
So. 568 beams remain.
