Question

I talk to an average of 8 customers per hour during an 8 hour shift and need to increase the amount of customers i help by 20%, how many customers do i need to help every hour to achieve this

Answer 1

The number of customer needed to achieve is 34

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 ×
`(1+(\textrm rate)/(100))^(n)`

or, The number of customer after 8 hours = 8 ×
`(1+(\textrm 20)/(100))^(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
