Question

solve b=33a to determine minimum furnace output for a house of 2300 feet squared

Answer 1

Hi, Ashley,

     b=minimum furnace output                          a=2300 ft²=area of a house   b=33 times (area)

Suppose you had a smaller house of 1, 200 sq. ft, you would solve with substitution:  b= 33(1,200.)=39,600 BTU's

Now do a= 2300 and multiply, and you are done.  The answer is in BTU's, which is a standard measurement for heat output.

I hope that this helps.                               Susan C.

Answer 2

well, the only thing for which we can solve is a;  a = b/33.
