The formula y equals x - 0.25 gives the sale price y for an item originally costing x dollars that was reduced by 25%. Find the sales price of a pair of jeans that originally cost $40
It be $30 because you take the 40 and times it by the .25 the number you get which in this case is 10 you subtract that number from the original cost so 40-10= 30 that being your final answer.
