Answer:
The replacement cost of 20% AC is $55,158,336
A is correct.
Explanation:
The manufacturing cost of an air-conditioning unit is $544 and the full-replacement extended warranty costs $113.
Total cost per air-conditioning with full replacement = 544+113 = $657
If the manufacturer sells 506,970 units with extended warranties and must replace 20% of them as a result.
Number of product for replace = 20% of 506,970 = 0.20 x 506970 = 101394
Note: Replacement cost is equal to manufacturing cost.
Replacement cost = Manufacturing cost = $544
Number of product for replacement = 101394
Total cost for replacement = 101394 x 544 = $55,158,336
Hence, The replacement cost of 20% AC is $55,158,336
