Three regional offices are responsible for completing similar types of cases and have been working on their cases separately. To better manage caseload fluctuations in future quarters, the caseload will be electronically distributed across offices. Each employee can complete approximately 200 cases per quarter. The table below indicates last year's caseload. If next year's caseload matches the previous pattern, but doubles in volume, what is the total number of employees that will be needed in the quarter with the highest overall caseload? Office A Office B Office C 1st quarter 1,000 800 1,500 2nd quarter 1,200 700 1,300 3rd quarter 1,500 600 1,600 4th quarter 1,600 700 1,500
