During a one day sale, a store sold each sweater of a certain type for 30$ more than the store's cost to purchase the sweater. How many sweaters were sold during the sale?
(1) During the sale, the total revenue from the sale of these sweaters was 270$
(2) During the sale, the store sold each of these sweaters at a price that was 50% greater than the store's cost to purchase each sweater.
OA is C.
store cost X
selling price x+30
number sweates sold Y
so revenue (prize - cost): y(30+x) - yx =270 ; 30y=270 ...hence a, what i am missing ??? pls explain
