For (a+b)^3 is:
1a^3+3a^2b+3ab^2+1b^3
8x^2+36x^2+54x+27
So the constant term is b^3=3^3=27



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
