1. jim_thompson5910

how far did you get

2. Luigi0210

you can set up the equations and matrix right?

3. lala2

im not sure.. I need a lot of guidence

4. Luigi0210

define variables: what each variable represents like x could be muffins and y is beverages

5. lala2

now what?

6. Luigi0210

set it up as a system of equations

7. Luigi0210

sorry about that bud, just working out the problem. This is how you would set it up as: 3.5x+1.75y=87.5 x+y=32 ------------------------------------- x=muffins ; y=beverages

8. Luigi0210

I wouldn't leave you hanging like that. ^_^ And yes, those are the equations, now set them up as matrices

9. Luigi0210

and matrices are the same as equations.. without the variables

10. lala2

ok im looking it up!

11. lala2

umm.. could you tell me how to set up the matrix

12. Luigi0210

|dw:1370383335499:dw|

13. Luigi0210

because a system of equations is basically the same as a matrix

14. lala2

oh its exactly the same!

15. lala2

ok I get it

16. Luigi0210

here if it helps I'll post my answer key:

17. lala2
