OA=C

Given: $$p=c+30$$

(1) (Revenue) = (price) * (# of sweaters sold) --> $$270=p*n=(c+30)n$$. Not sufficient to determine $$n$$.

(2) $$p=1.5c=c+30$$ --> $$c=60$$. Not sufficient.

(1)+(2) $$c=60$$ and $$270=(c+30)n=90n$$ --> $$n=3$$. Sufficient.

The total revenue from the sale is (price per unit) * (# of units sold).

(Selling price per unit) - (Cost price per unit) = (Gross profit from one unit).
