Answer:
one binder for $3.70
Step-by-step explanation:
The cost of 5 binders and 3 folders = $23.00
The cost of 5 binders and 1 folder = $20.00 [ 2 folders less ]
Cost of 2 folders = 23 - 20 = $3.00
Cost of 1 folder = [tex]\frac{3}{2}[/tex] = $1.50
The cost of 5 binders = 20.00 - 1.50 = $18.50
The cost of 1 binder = [tex]\frac{18.50}{5}[/tex]
= $3.70
The cost of one binder is $3.70
