Challenge Problems

Push your limits with challenges.

Question 1

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?

💡 Hint: Use unit cost calculations to find the total.

Question 2

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.

💡 Hint: Calculate the increase based on percentage change.
