A software QA team is required to test an average of 180 cases per day over a 30 -day sprint. For the first 12 days, the team averaged 150 cases each day. How many cases per day must the team average over the remaining 18 days to meet the overall requirement?

Explanation	Calculations	Help
$We name x as the average number of cases per day over the remaining 18 days.$	$x = average cases per day over the remaining 18 days$
$We calculate the total number of cases required for the 30-day sprint.$	$Total cases required = 180 \times 30 = 5400$
$We calculate the number of cases already tested in the first 12 days.$	$Cases in first 12 days = 150 \times 12 = 1800$
$We find how many cases remain to be tested in the remaining days.$	$Remaining cases = 5400 - 1800 = 3600$
$We express the remaining cases as the product of the daily rate x and the number of days left.$	$x \times 18 = 3600$
$We solve for by dividing both sides by 18 and simplifying the fraction.$	$x = \frac{3600}{18} = \frac{18 \times 200}{18} = 200$	Theory & Tactics Method Card FDPR2-A Click to view full details
