Let: x = number of copies sold
We can formulate the following equation to solve for x:
1.50x - 0.9x - 600 = 0
x = 1000
Therefore, the club must sell 1000 copies to break even. Among the choices, the correct answer is A.
1 mg = 0.001 grams. therefore 2000 mg = 2 grams
There are three more angles with the same measure. A pair of corresponding angles and a pair of vertical angles.
