A patient is on a special diet to help them gain weight. After starting at 113 pounds, the patient now weighs 137 pounds at their most recent checkup. What is the percentage change in the patient's weight?

The percentage change in the patient's weight is calculated by taking the weight gained (24 pounds), dividing it by the original weight (113 pounds), and then multiplying by 100%. This results in a percentage change of approximately 21.24%.

Explanation:

To calculate the percentage change in the patient's weight, we will use the formula for percentage change which is the change in value divided by the original value, multiplied by 100%. The patient's original weight was 113 pounds, and their new weight is 137 pounds. To find the change in weight, we subtract the original weight from the new weight:

Change in weight = New weight - Original weight = 137 pounds - 113 pounds = 24 pounds

Next, we divide this change by the original weight and multiply by 100 to get the percentage:

Percentage change = (Change in weight / Original weight) imes 100% = (24 pounds / 113 pounds) imes 100% \/= 21.24%

Therefore, the percentage change in the patient's weight is approximately 21.24%.
