The manufacturing cost of an air-conditioning unit is $544, and the full-replacement extended warranty costs $113. If the manufacturer sells 506,970 units with extended warranties and must replace 20% of them as a result, how much will the replacement costs be? (Note: Assume manufacturing costs and replacement costs are the same.)
a.
$55,158,336
b.
$11,457,522
c.
$2,129,274
d.
$66,717,252
