Carter is twice as tall as his 24" tall dog. Betty is 12" shorter than Carter. How tall is Betty in feet? Give me reasons, before answering the question
Carter is twice as tall as 24" dog so he is 2 * 24 = 48". Betty is 12" shorter than Carter so Betty is 48 - 12 = 36" tall. 12" is the same as 1 foot so Betty is 36 / 12 = 3 feet tall. So the final answer is 3.
