A single-subscripted array can be used to solve the problem of paying salespeople in different ways.
Step-by-step explanation:
A single-subscripted array can be used to solve the problem of paying salespeople in different ways. Each salesperson's compensation plan can be stored in the array, with each element representing the type of payment plan they are on. For example, the array could have elements like 'Fixed salary', 'Commission only', 'Base salary plus commission', and 'Hourly wage'. By accessing the elements of the array, the company can determine the appropriate payment for each salesperson.
