Answer:
$8,639
Step-by-step explanation:
The computation of the incremental annual cash flow is shown below:
= Increase in cash flows due to decrease in expenses × (1 -tax rate)+ Depreciation benefit × tax rate
= $14,000 × (1 - 0.34) + -$1,767 × (0.34)
= $9,240 - $600.78
= $8,639
Working note
Depreciation benefit = Depreciation on new machine - Depreciation on the old machine
= $89,000 ÷ 10 years - $64,000 ÷ 6 years
= $8,900 - $10,667
= -$1,767
