Answer:

Equation: 7n = 8.61

Solution: n = $1.23

Step-by-step explanation:

7 binders = $8.61

1 binder = $n

The price of one binder is seven times the price of 7 binders.

7n = The price of 7 binders

The price of 7 binders is $8.61

7n = $8.61

Divide both sides of the equation by 7

n = $1.23
