<h3>Answer: D) Midsegment Theorem for Trapezoids</h3>

Assuming that the bottom horizontal segment is 9 units long, this would mean that x = 5 on top, added to the 9 on the bottom, gives 5+9 = 14. This cuts in half to get 14/2 = 7, which is the length of the midsegment of the trapezoid.

In short: add the parallel sides of the trapezoid, then cut that result in half. This will yield the midsegment.

Answer:

Markup = [(Revenue – COGS) / COGS] X 100.

Markup = (Gross Profit / COGS) X 100.

Markup = [(Revenue – COGS) / COGS] X 100.

Markup = [($400 – $250) / $250] X 100.

Selling Price = [(Markup X COGS) + COGS] X 100.

Selling Price = (Markup X COGS) + COGS.

Selling Price = (0.50 X $100) + $100.
