The total decrease in net income by replacing the current machine with the new machine (ignoring the time value of money) is $22,000

Explanation:

Taking note of "Ignoring the time value of money "

The total decrease in net income by replacing the current machine with the new machine = (-Initial cash outlay + Saving in annual variable) + manufacturing costs * Number of year

The total decrease in net income by replacing the current machine with the new machine = -$120000 + $22000 + $19,000 *4

=  (-$120000 +  $22000)+ $19,000 *4

= -$98,000 + $76,000

= -$22,000

Conclusion: The total decrease in net income by replacing the current machine with the new machine = $22,000
