2772 times

Explanation:

On average, a refrigerator door is opened 22 times each day.

Len has two refrigerators in his house.

Step 1

From the above question:

1 refrigerator = 22 times

2 refrigerators = 2 × 22 times

= 44 times.

Hence, Per days 2 refrigerators is opened 44 times

Step 2

In 1 week = 7 days =(For 2 refrigerators)

1 day = 44 times

7 days = x times

x = 7 × 44

x = 308 times.

Hence in 1 week, the 2 refrigerators are opened 308 times

Step 3

How many times in a 9−week period are the refrigerator doors opened

1 week period = 308 times

9 week period =

308 times × 9

= 2772 times
