Sam bought a new skateboard. The sales tax rate is 6%. The equation to find the total cost is where c is the cost of the skateboard and t is the total cost. Which variable is the independent variable?
A. c
B. t
C. There is no relationship between the variables.

The independent variable is the cost of the skateboard, c.

The dependent variable would be the total cost, t.

The best way to understand this is that the cost of the skateboard from the company is not going to change based on a sales tax rate., But the overall total cost could change depending on what the sales tax rates are.

The total cost would be dependent upon the sales tax rate.
