A customer service center must answer an average of 120 calls per day over a 30 -day month. During the first half of the month, the center answered an average of 105 calls per day. What average number of calls per day must the center answer in the second half of the month to meet the monthly target?

Explanation	Calculations	Help
$We name x as the average calls per day the center must answer in the second half of the month.$	$x = average calls per day in the second half of the month$
$We calculate the total calls needed for the entire 30-day month.$	$Total calls needed = 120 \times 30 = 3600$
$We calculate the calls answered in the first 15 days.$	$Calls in first half = 105 \times 15 = 1575$
$We determine the remaining calls that must be answered in the second half by subtracting.$	$Remaining calls = 3600 - 1575 = 2025$
$We set up an equation relating x to the remaining calls over 15 days.$	$x \times 15 = 2025$
$We solve for x by dividing both sides by 15 and simplifying the fraction by breaking it into parts.$	$x = \frac{2025}{15} = \frac{1500}{15} + \frac{525}{15} = 100 + 35 = 135$	Theory & Tactics Method Card CALC2-E Click to view full details
