Billy can spit a watermelon seed 30 inches. Madison can spit a watermelon seed 20% farther than Billy. Ryan can spit a watermelon seed 50% shorter than Madison. How far can Ryan spit a watermelon seed? Give the rationale and then the answer.
Let's think step by step. Madison can spit a seed 20% farther than Billy's 30 inches so that's .20 * 30 = 6 inches farther. Billy spits a seed 30 inches and Madison can spit 6 inches farther for a total of 30 + 6 = 36 inches. Ryan can spit a seed 50% shorter than Madison's 36 inches for a total of .50 * 36 = 18 inches.. The answer is: 18.
