You can put this solution on YOUR website! 550=75a+34c let a=1,2,3,4,5,6,7 then c=13,11,9,5,5,2,0
550=75+34c
34c=550-75
34c=475
c=425/34
c=13.97
-------------
550=75*2+34c
34c=550-150
34c=400
c=400/34
c=11.8
-------------
550=75*3+34c
34c=550-225
34c=325
c=325/34
c=9.55
--------------------
550=75*4+34c
34c=550-300
34c=250
c=200/34
c=5.88
-----------------
550=75*5+34c
34c=550-375
34c=175
c=175/34
c=5.15
-------------------
550=75*6+34c
34c=550-450
34c=100
c=100/34
c=2.94
-------------------
550=75*7+34c
34c=550-525
34c=25
c=25/34
c=.73
------------------
