So in order to find this, you have to figure out how much each folder and notebook cost by itself. You would need to do 7.00/4 and 2.5/10. So each folder is $.25 and each notebook is $1.75. Then you just add it all up (or multiply). So, .25×6=1.5
1.75×5=8.75
Answer: $1.5 for 6 folders and $8.75 for 5 notebooks
