4. Sarah brought two 16-ounce water bottles with her on a bike ride. She drank 75% of one of the bottles and 50% of the other by the halfway point of her ride. How many ounces of water does she have remaining? (Please enter your answer as a whole number.)
75 percent of 16 is 16 divided by 4 times 3 16/4=4×3=12 75 percent of 16 is 12 16-12=4 ounces remaining at the moment 50 percent or half of 4 is 2 so 4-2=2 ounces remaining the answer is: 2 ounces
