*$45,000/$85,500 × $18,000 = $9,474; 45,000 /85,500 × 18,000 = 9,474
$10,000 – $9,474 = $526 10,000 – 9,474 = 526
← direct fixed cost, system A
** $32,500/$85,500 × $18,000 = $6,842; 32,500 /85,500 × 18,000 = 6,842
$18,000 – $6,842 = $11,158 18,000 – 6,842 = 11,158
← direct fixed cost, system B
*** $8,000/$85,500 × $18,000 = $1,684; 8,000 /85,500 × 18,000 = 1,684
$2,700 – $1,684 = $1,016 2,700 – 1,684 = 1,016
