The first furnace, the companion, costs
C = 520 + 225 (L) ... where L = load and 225 is 22.5 cents
The dryer the other side, the dress cost Whirlwind
C = 735 + 158 (L ).... The dryer is more expensive
520 +, 225 L = 735 + 158 L
L 225-158 L = 735 to 520
0.067L = 215
L = 3208.9 or 3209, when the charge runs expenses are almost identical
