help asap please.

suppose c and d cary inversely, and d = 2 when c = 17.

a. write an equation that models the variation.
b. find d when c = 68.

what i have so far is
d = k/c
2 = k/17
k = 2(17) = 34

^^ is that all or do i do more? i’m not so sure

well, your equation was
d = k/c , and you found k = 34
so the equation is d = 34/c

then for b) when c = 68 ,
d = 34/68 = 1/2
