Answer:
B. 9
Step-by-step explanation:
We are given that <em>y</em> varies inversely with <em>x</em>. Recall that inverse variation has the form:

Where <em>k</em> is the constant of variation.
We are given that <em>y</em> = 18 when <em>x</em> = 12. Hence:

Solve for <em>k. </em>Multiply both sides by 12:

Thus, our equation is:

We want to find <em>x</em> when <em>y</em> = 24. Substitute:

Cross-multiply:

Divide both sides by 24. Hence:

Our answer is B.
Unit cost to sales price is 1:4.....or 1/4
1 / 4 = 33.85 / s.....1 unit cost to 4 sales price = 33.85 unit cost = s sales price
cross multiply
(1)(s) = (4)(33.85)
s = 135.40 <=== selling price
