The only acceptable way to divide words at the end of a line is?

the saving company have is: 24  *$1.25 = 30

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

My

We need to caculate the surface areas of

Box 1 = 2lw+2lh+2hw = 2*20*4 + 2*20*6 + 2*6*4 = 448

Box 2 = 2lw+2lh+2hw = 2*15*8 + 2*15*4 + 2*4*8 = 424

So the differences in surface areas of the two boxes is:

448  - 424

= 24  

So the saving company have is: 24  *$1.25 = 30

Hope it will find you well.
