I’m pretty sure it’s 8 I could be mistaken though

Answer:

  • The number that should go in the box in order to complete the expression is:  8
  • i.e. the expression is: 2(8x)+5(8)

Step-by-step explanation:

It is given that:

Kali earns $ 8 per hour.

This means that if she works for n hours then this earning for n hours will be given by: $ 8n

She works x hours on both Monday and Tuesday.

This means that the earning of x hours is: $ 8x

and hence the earning for both Monday and Tuesday is:$ 2(8x)

She also worked for 5 hours on Thursday.

Hence, the earning for Thursday is: 5×8=40

The total earning of the week is given by:

                            2(8x)+5(8)
