the formula a = 46c gives the floor area a in square meters that can be wired using circuits

Question

A.solves a = 46c for c
b. if a room is 322 square meter, how many circuits are required to wire this room?

Answer 1

A. a = 46c --> Divide off 46. c = a/46.

B. a = 322 square meters. a = 46c, so 322 = 46c. c = a/46, so c = 7. 7 circuits are required.
