3/4 foot is 9 inches, and 4 1/2 feet is 54 inches, so, 54/9 makes exactly 6 pieces of string.
Answer:
8x-9y=31
Step-by-step explanation:
Rate of discount = (old price - new price)/old price x 100 = (1280 - 1030)/1280 x 100 = 250/1280 x 100 = 19.5%
Amount of discount = old price - new price = $1,280 - $1,030 = $250
