i need to know how to solve this to get the cost of each item?

- MATH -
**Steve**, Friday, February 8, 2013 at 4:03pmjust substitute the various quantities:

c+s+t=300

2s+s+t=300

3s+t = 300

3(2t+40)+t = 300

6t+120+t = 300

7t + 120 = 300

7t = 180

odd that you don't get an exact divisor.

Oh well, get t and then you can get c and s.
