a discount electronics store normally sells all merchandise at a discount of 10 percent to 40 percent off the suggested retail price . if , during a special sale , an additional 5 percent were to be deducted from the discount price , what would be the lowest possible price of an item costing $ 500 before any discount ?
"original price : 500 $ max first discount = - 40 % thus : 500 â ˆ — ( 1 â ˆ ’ 40 / 100 ) = 300 second discount on the discounted price = - 20 % thus : 300 â ˆ — ( 1 â ˆ ’ 5 / 100 ) = 285 answer b ."
multiply(500, divide(add(40, 5), const_100))
