The formula b=34a is used in New England to estimate the minimum furnace output, b, in BTUs, for a modern house with a square feet of flooring.
a)Determine the minimum furnace output for a 16000 ft^2 modern house
b)Solve for formula a

a. Wow, is that a palace? Most city lots don't have 16,000 sq.ft! Anyway,
b=34*16000 BTU
=544,000 BTU
(costs $5/hour to heat the place, or palace).
b=34a
b/34=a
a=b/34 sq.ft.
