Answer 1

2(8x)+5(8)

8

The computation of the number that should go to finished the expression is as follows:

Given that

Kali earns $ 8 per hour.

If she worked for n hours so it would be $8n

And she worked on both monday and tuesday for x hours

So, the x hour earning is $8x and for both days it would be $2 (8x)

In addition to this, she worked 5 hours on thursday

So her earnings on thursday is 5×8=40

So, the total earning for the week is

2(8x)+5(8)
