Two coworkers picked up some writing instruments at the office supply store. Janice selected 6 boxes of pencils and 10 boxes of ballpoint pens, paying $36. Next, Kendra spent $34 on 4 boxes of pencils and 10 boxes of ballpoint pens. How much does a box of each cost?

i do not know but i am guessing 1dollar a box for the pencils and 3 dollars a box for the pens
hope it helps
If the price of a box of pencils is $p, and ballpoints cost $b then
6p+10b = 36
4p+10b = 34
subtract to see that
2p = 2
Now finish it off
@oobleck what
i am saying that each box of pencils cost 1$ and each box of pens cost 3$
