Answer:

160.

Step-by-step explanation:

Work out the innermost parentheses first:

{[9 x (7.3+10.7)} - 5} + [3 x (7.8 - 6.8)}

= {[9 x 18} - 5} + [3 x 1}

= {162 - 5} + 3

= 160.

Signal mistakenly produced 1,000 defective cell phones. the phones cost $60 each to produce. a salvage company will buy the defe

zhannawk [14.2K]

We are asked to solve for the incremental net income from reworking the phones.
Number of items = 1000
Production Cost = 1000*$60 = $60,000
Salvage value = 1000*$30 = $30,000
Rework Cost = 1000 *80 = $80,000
Price when resold = 1000 * $120 = $120,000

Incremental Net = $120,000 + $30,000 - $60,000 -$80,000
Incremental Net = $10,000

The answer is $10,000.
