Using algebra, how would you go about solving this question:
A merchant was selling an item at a certain price, then marked it down 20% for a spring sale. During summer, he marked the item down another 20% from its spring price. If the item sold at the summer price, what percent of the original price did it sell for ?
U need to post it on Math forum
first mark down=.8x
second mark down=.64x
so the item was sold for 36%off the original price or 64% of the original
