THe formula b=26a is used in New England to estimate the minimum furnace output, b, in BTU's for a modern house with a square feet of flooring
a) determine the minimum furnace output for a 1700 ft(squared) modern house
.
Plug in the given number into:
b=26a
b=26(1700)
b = 44200 BTU
.
b) solve formula for a
b=26a
Dividing both sides by 26:
b/26 = a
or
a = b/26
