Differential Analysis In each of four independent cases, the amount of differential revenue or differential cost is as follows (parentheses indicate decreases): Increases (decreases) in: Revenue Costs 1 2 3 4 $14,000 $0 ? ? ? ? $(16,000) $0 For each case, determine the missing amount that would be necessary for the net differential amount to be: a. $10,000 Use a negative signs with answers to reflect decreases. Increases (decreases) in: Revenue Costs 1 2 3 4 $ $14,000 4,000 $0 $ 10,000 x 6,000 * $ $(16,000) 10,000 $0 b. ($2,000) Use a negative signs with answers to reflect decreases. Increases (decreases) in: Revenue Costs Check 1 2 3 4 $14,000 $ 16,000 $ $0 $ 2,000 18,000 * $ 2,000 x $(16,000) $0
