Final answer:
Jennifer's height is 44 inches.
Step-by-step explanation:
To find Jennifer's height, we start by setting up an equation using the information given. Let's say Jennifer's height is x. According to the problem, Marco's height is 3 inches less than 1.5 times Jennifer's height, which can be written as: 63 = 1.5x - 3. Now, we can solve for x. First, we add 3 to both sides of the equation to isolate 1.5x: 63 + 3 = 1.5x. Simplifying, we get: 66 = 1.5x. To find x, we divide both sides by 1.5: x = 66 ÷ 1.5. Evaluating the division, we find that Jennifer's height, x, is 44 inches. Therefore, the correct answer is B. 44 in.
