Answer:
$659,277
Step-by-step explanation:
The computation of the manufacturing labor dollars per year over the three year period of performance is shown below:
For 3 year it is
= 3 × 1,800 hours × $31
= $167,400
For 4.5 years, it is
= 4.5 × 1,800 hours × $31 × 1.025
= $257,377.50
Foe 4 years, it is
= 4 × 1,800 hours × $31 × 1.025 × 1.025
= $254,499.50
So, the manufacturing labor dollars per year is
= $167,400 + $257,377.50 + $254,499.50
= $659,277
