Austin is a surfer. He took a trip to the beach during surfing season and the highest wave he caught was two feet higher than four times his height. The shortest wave he caught was four feet higher than his height. The shortest wave was three feet higher than his 7-foot surfboard is long. How tall was the highest wave Austin caught? Let's answer step by step:
The shortest wave was 7 + 3 = 10 feet tall. Austin is 10 - 4 = 6 feet tall. Thus, the highest wave Austin caught was 6 * 4 + 2 = 24 + 2 = 26 feet tall. The answer: 26.
