Brett and Juanita each have a glass containing 300 mL of water. Brett pours half of his water out and then Juanita pours 20% of her water into Brett’s glass. What volume of water is now in Brett’s glass?
Pick one
Solution
After Brett pours half of his 300 mL of water out, he has 150 mL of water remaining in his glass.
Juanita then pours 20% of her 300 mL or 0.20×300 mL=60 mL of water into Brett’s glass.
The volume of water now in Brett’s glass is 150 mL+60 mL=210 mL.
