Ineed to increase the number of customers by 20% daily, i talk to an average of 8 customers per hour during an 8 hour shift so now ill need to talk to how many customers per day?

The number of customer per day is 10.

Step-by-step explanation:

Given : I need to increase the number of customers by 20% daily, I talk to an average of 8 customers per hour during an 8 hour shift.

To find : How many customers per day?

Solution :

We have an average of 8 customers.

Increase the number of customers by 20% daily.

i.e. increased number will be 20% of 8,

i.e. 1.60 customer per hour during an 8 hour shift.

So,

Approximately the number of customer per day is 10.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
