Giuseppe wants to try two different kinds of soup. one soup has 60 mg sodium per ounce. the other has 80 mg sodium per ounce. giuseppe wants to consume no more than 1,000 mg sodium. which inequality represents the situation?

This is the theory of inequalities. To solve the question we proceed as follows;
Suppose Giuseppe requires x mg of 60 mg sodium per ounce and y amount of 80 mg sodium per ounce. Then the total amount required will be:
60x+80y≤1000
Dividing through by 20 we get:
3x+4y≤50
The answer is:
3x+4y≤50

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.

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.
