stellarik [79]

Answer:

146 people

Step-by-step explanation:

The formula for mean = sum of values/number of values

For Monday to Friday , the average number of people that came = 98

Hence, the total number of people that came is calculated as:

Number of people that attended Monday to Friday = 98 × 5 = 490 people

The number of people that came on Saturday = 162 people

The mean average for the whole week is 114.

The number of days in a week = 7 days

The number of people that came in on Sunday is represented = x

Therefore,

490 + 162 + x/7 = 114

Cross Multiply

652 + x = 798

x = 798 - 652

x = 146 people

Therefore, 146 people visited on Sunday
