Final answer:
Santa's weight needs to increase by approximately 57% to reach his goal weight of 275 pounds.
Step-by-step explanation:
To find the percent increase in Santa's weight, we first calculate the difference between his goal weight and his current weight: 275 - 175 = 100 pounds.
Next, we find the percent increase by dividing this difference by his current weight and multiplying by 100: (100 / 175) * 100 = 57.14%.
Therefore, Santa's weight needs to increase by approximately 57% to reach his goal weight of 275 pounds.
