Given :
On average, a refrigerator door is opened 99 times each day.
Len has two refrigerators in his house.
To Find :
How many times in a 8−week period are the refrigerator doors opened.
Solution :
Number of times door opened for 2 refrigerator , n = 99×2 = 198.
Number of days in 8 week , d = 8×7 = 56 days.
So, total number of times doors open in a period of 8-week is :
[tex]T=n\times d\\\\T=198\times 56\\\\T=11088\ times[/tex]
Therefore, refrigerator doors are opened about 11088 times.
Hence, this is the required solution.
