Final answer:
The equation (×)(0.6) = 86.46 represents determining the amount of tax added to a purchase after a 6% tax rate.
Step-by-step explanation:
The equation (×)(0.6) = 86.46 represents determining the amount of tax added to a purchase after a 6% tax rate, which is option C.
In this equation, the unknown value is represented by "×", and it is being multiplied by 0.6. The result of this multiplication is equal to 86.46, which represents the amount of tax added.
In this scenario, the equation can be solved by dividing both sides of the equation by 0.6 to find the value of "×". So, option C, determining the amount of tax added to a purchase after a 6% tax rate, is the scenario modeled by this equation.
