a. Since c and d vary inversely, we can write the equation as c * d = k, where k is a constant.
Given that d = 2 when c = 17, we can plug these values into the equation:
17 * 2 = k
34 = k
Therefore, the equation that models the variation is c * d = 34.
b. To find d when c = 68, we can plug c = 68 into the equation and solve for d:
68 * d = 34
d = 34 / 68
d = 0.5
So, when c = 68, d = 0.5.
Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.
