Final answer:
Grace can be any height greater than 56 inches.
Step-by-step explanation:
We are given that Grace is at least 8 inches taller than her younger sister, who is 4 feet tall. To find the maximum height of Grace, we need to convert the height of her sister into inches. Since 1 foot is equal to 12 inches, 4 feet is equal to 4 x 12 = 48 inches. Therefore, the inequality representing the maximum height of Grace can be written as:
Grace's height > 48 + 8
Simplifying, we have:
Grace's height > 56 inches
So, Grace can be any height greater than 56 inches.
