Answer:
The number of customer needed to achieve is 34
Step-by-step explanation:
Given as :
The number of customer per hour = 8
The time taken = 8 hours
The rate of increase = 20 %
Let The increase in number of customer after 20 % increment = x
So , The number of customer after n hours = initial number ×
or, The number of customer after 8 hours = 8 ×
or, The number of customer after 8 hours = 8 × 4.2998
∴The number of customer after 8 hours = 34.39 ≈ 34
Hence The number of customer needed to achieve is 34 answer
A geometric series is written as , where
is the first term of the series and
is the common ratio.
In other words, to compute the next term in the series you have to multiply the previous one by .
Since we know that the first time is 6 (but we don't know the common ratio), the first terms are
.
Let's use the other information, since the last term is , we know that
, otherwise the terms would be bigger and bigger.
The information about the sum tells us that
We have a formula to compute the sum of the powers of a certain variable, namely
So, the equation becomes
The only integer solution to this expression is .
If you want to check the result, we have
and the last term is
