I need to do this in a chart form and have already set it up but I am lost on what to do next.

- algebra -
**Reiny**, Tuesday, January 17, 2012 at 5:31pmnumber of 15 cent stamps --- x

number of 20 cent stamps --- 4x

number of 40 cent stamps ---- 300 - 5x

15x + 20(4x) + 40(300-5x) = 7380

solve for x

plug that into 300-5x

Chart form ???

What grade level is this ?
