You can put this solution on YOUR website! 3 bags of chips and 2 container of dip cost $9. However, 5 bags of chips and 7 containers of dip cost $26. What is the cost of one bag of chips and one container of dip?
Let the cost of chips be "c" and the cost of dip be "d".
3c + 2d = $9 .. equation 1
5c + 7d = $26 .. equation 2
If c = 1,
3(1) + 2d = $9
3 + 2d = $9
2d = 9-3
d = 6/2
d = $ 3
Put c = 1 and d = 3 into equation 2
5(1) + 7(3) = 5 + 21 = 26
Therefore,the packet of chips is $1 and the dip cost $3.
