The manufacturing cost of a cell phone was $124. Sellers first marked up the cost by 20 percent. Sales were poor, so sellers decreased the markup to 15 percent. Calculate the old and new selling prices. A.
old price: $170.00; new price: $148.80
B.
old price: $142.60; new price: $148.80
C.
old price: $148.80; new price: $142.60

if the phone costs $ 124 ,and first was marked up by 20 % it means that it was for sale for

124+(124*20)100=124+24.80= $148.80

if the seller decreased the mark up to 15% then the phone costs now

124+(124*15)/100=124+18.60= $ 142.60
