Explanation
Problem Analysis Let's analyze the problem. We need to determine who recovers their investment faster, Person A or Person B. To do this, we'll calculate the time it takes for each person to recover their investment, considering their lost income during college, the cost of college, and their increased salary after graduation.
Calculating Lost Income First, we calculate the lost income for Person A during their 3 years of college: L os t I n co m e A = S a l a ry P r i or t o S c h oo l A × Y e a rs A tt e n d in g C o ll e g e A = $18 , 000 × 3 = $54 , 000 Next, we calculate the lost income for Person B during their 4 years of college: L os t I n co m e B = S a l a ry P r i or t o S c h oo l B × Y e a rs A tt e n d in g C o ll e g e B = $27 , 000 × 4 = $108 , 000
Calculating Total Investment Now, we calculate the total investment for Person A, which includes the lost income and the cost of college: T o t a l I n v es t m e n t A = L os t I n co m e A + T o t a l C os t o f C o ll e g e A = $54 , 000 + $45 , 000 = $99 , 000 Similarly, we calculate the total investment for Person B: T o t a l I n v es t m e n t B = L os t I n co m e B + T o t a l C os t o f C o ll e g e B = $108 , 000 + $30 , 000 = $138 , 000
Calculating Increased Salary Next, we determine the increase in salary after graduation for Person A: I n cre a se d S a l a r y A = S a l a ry U p o n G r a d u a t in g A − S a l a ry P r i or t o S c h oo l A = $33 , 000 − $18 , 000 = $15 , 000 And for Person B: I n cre a se d S a l a r y B = S a l a ry U p o n G r a d u a t in g B − S a l a ry P r i or t o S c h oo l B = $37 , 000 − $27 , 000 = $10 , 000
Calculating Recovery Time Now, we calculate the time it takes for Person A to recover their investment: T im e t o R eco v e r A = I n cre a se d S a l a r y A T o t a l I n v es t m e n t A = $15 , 000 $99 , 000 = 6.6 ye a rs And for Person B: T im e t o R eco v e r B = I n cre a se d S a l a r y B T o t a l I n v es t m e n t B = $10 , 000 $138 , 000 = 13.8 ye a rs
Comparing Recovery Times and Conclusion Comparing the recovery times, Person A recovers their investment in 6.6 years, while Person B takes 13.8 years. Therefore, Person A recovers their investment in a shorter amount of time.
Examples
Understanding the return on investment (ROI) for education is crucial in making informed career decisions. For instance, consider a student deciding between a shorter, less expensive program and a longer, more costly one. By calculating the lost income during studies, the total cost of education, and the potential increase in salary after graduation, the student can estimate how long it will take to recoup their investment. This analysis helps in choosing the program that offers a quicker financial recovery and better long-term financial benefits, ensuring a more strategic approach to education and career planning.
