Abookstore is having a sale in which you can get 4 notebooks for $7.00 and 10 folders for $2.50.how much will it cost rico to buy 5 notebooks and 6 folders

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
$1.5 for 6 folders and $8.75 for 5 notebooks

Is there a picture of a graph or whatever that goes along with this?
