The cost for andrea to produce several units of a certain item is $336 plus $12 per unit. she sells this item for $28 per unit.
how many units of the item must she produce and sell so that the amount of money she earns in sales equals the amount of money she spends in production costs? how much money would that be?

Profit will be achieved when the money earned is greater than the money spent so,
336 + (n*12) = n*28  any subsequent units sold would result in profit
336 = 28n - 12n
336 = 16n
=>  n = 336/16 = 21
21 units must be sold to draw even any more would result in profit

750

Step-by-step explanation:

Applying for credit from any place pulls your credit report.  When your credit report is pulled, your score decreases some.  

However, this will not have a large effect on your score, so 750 would most likely be the new score.

Getting a store credit card affects the credit score a little bit, so the answer would likely be D.
