A new shopping mall records 120 total shoppers on their first day of business. Each day after that, the

number of shoppers is 10% more than the number of shoppers the day before.

What is the total number of shoppers that visited the mall in the first 7 days?

Round your final answer to the nearest integer.

Let, No of shoppers on first day = a

No of shoppers on second day = b

Similarly till seventh day,

Therfore shoppers on seventh day=

a + b + c + d + e + f + g

As mentioned ,number of shoppers is 10% more than the number of shoppers the day before. i.e we can understand that a to g all are 1.1 times bigger than the previous letter.

That means all are in geometric series.

We know the formula for sum of geometric series is,

=

That is,

a = 120

r = 1.1

n = 7

=

=  

= 212.58

Approximately

this is not the answer this is just a question. is this middle school math?
