Answer:
Each folder was 81 cents
Step-by-step explanation:
First we subtract the given values from 15.6 to find out how much she has left when she buys the folders.
15.6-3.4-1.98-8.6=1.62
She has $1.62 remaining and she buy two identical folders. That means both were at the same price. So we just need to divide by two to find the cost of each individual folder.
1.62/2=.81
Each folder was 81 cents
