Step-by-step explanation:
We know that:
<span>rate = 0.15 heaters /labor hour</span>
labourer time = 160 hours /
month
goal = 57,600 heaters / year
We can solve this problem by
simply looking at which ratios will cancel out the units:
<span>number of labourers = (57,600
heaters/year) / [(0.15 heaters /labor hour) * (160 hours/month) * (12 month/year)</span>
<span>number of labourers = 200</span>
