Answer 1

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 :

`T=n* d\\\\T=198* 56\\\\T=11088\ times`

Therefore, refrigerator doors are opened about 11088 times.

Hence, this is the required solution.
