Question: Haley grows at the rate of 3 inches every year. If she is currently 20 inches tall, what will be her height after 10 years? Think carefully first, then make a decision:
After 10 years, growing at the rate of 3 inches every year, Haley will have grown by 3 * 10 = 30 inches. If she is currently 20 inches tall, her height after 10 years will be 20 + 30 = 50 inches. So the answer is 50.
