Question 5.
If a bulldozer’s cost per hour is $1200 and its adjusted productivity after applying various factors is 30 bank meters/hour, what is the total cost for moving 150 bank meters?
Show hintHide hint
Use unit cost calculations to find the total.
Question 6.
During a project, the soil density changes to require a higher correction factor than previously planned. If the original unit cost was $25, and your new factor raises costs due to reduced productivity, estimate the new cost assuming a 15% increase.
Show hintHide hint
Calculate the increase based on percentage change.
