Answer:
Steve will take 240 minutes or 4 hours.
Explanation:
Steve and Hillary can mow a lawn in 60 minutes by working together. However, Hillary works three times faster than Steve.
Let's assume Steve takes takes x minutes to mow alone.
This implies that Hillary can mow alone in x/3 minutes.
In a minute, Steve can mow 1/x of the lawn, so this means Hillary can mow 3/x of the lawn.
In a minute together then can mow,
= 
= 
In 60 minutes they can mow
= 
= 
This means that it takes 4 hours for Steve to mow the lawn alone.
Common between optimization using total value and optimization using marginal analysis is:
Both techniques require the conversion of all costs and benefits into a common unit of measurement.
What is the principle of optimization at the margin?
The Principle of Optimization at the Margin states that an optimal feasible alternative has the property that moving to it makes you better off and moving away from it makes you worse off.
Optimization using total value:
calculates the change in net benefits when switching from one. alternative to another.
optimization using marginal analysis:
calculates the net benefits of. different alternatives.
Total Value analysis :
has a wide range of applications. The analysis can be used to assess an organization's key impacts, or provide more detailed information such as an assessment of the life cycle impacts of a product.
marginal analysis:
is an examination of the additional benefits of an activity compared to the additional costs incurred by that same activity. Companies use marginal analysis as a decision-making tool to help them maximize their potential profits.

e. The term that indicates most people need to be incentivized to save: 4.Time preference
f. The result consumption exceeding income over a particular period: 5. Dissaving
