Person B recovers their investment in a shorter amount of time.
In order to determine the recovery time, divide the total cost of college by the salary that is earned after graduating from college.
Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations.
Recovery time = cost of college / salary after college
Recovery time for person A = $45,000 / $33,000 = 1.36
Recovery time for person B = $30,000 / $37,000 = 0.81
