The equation that can be used to find the cost of each binder n in dollars is 861=7n.
Given that the cost of 7 binders is $8.61.
We are required to form an equation that represents the total cost of each binder n in dollars.
Equation is like a relationship between all the variables that are expressed in equal to form.It may be linear equation or may be more types.
Suppose the cost of 1 binder is n dollar.
We know that the total cost is basically the product of price of 1 unit and number of quantities of units.
Total cost=Price of 1 unit* number of units
8.61=n*7
8.61=7n
Hence the equation that can be used to find the cost of each binder n in dollars is 861=7n.
