Anew 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.

answer:

first day there were 120 shoppers.

second day it increases by 10% which means 120(1.1)=132.

on third day it will be 10% more than previous day which means 132(1.1)=145.2

on fourth day it will be 10% more than the previous day which means 145.2(1.1)=159.72.

on fifth day it will be 10% more than previous day which means 159.72(1.1)=175.692.

on sixth day it will be 10% more than previous day which means 175.692(1.1)=193.2612.

on seventh day it will be 10% more than previous day which means 193.26121.1)=212.58732.

so the total number of shoppers that visited in first 7 days are = 120+132+145.2+159.72+175.692+193.2612+212.58732 = 1138.46052 that is 1138.5( by rounding off).
