Final answer:
To find the number of months it will take for Mr. Harris to weigh 220 pounds, divide the difference between his current weight and the target weight by the rate of weight loss.
Step-by-step explanation:
To find the number of months it will take for Mr. Harris to weigh 220 pounds, we need to calculate the difference between his current weight and the target weight. In this case, the difference is 260 pounds - 220 pounds = 40 pounds.
Since Mr. Harris loses 4 pounds per month, we can divide the difference by the rate of weight loss: 40 pounds ÷ 4 pounds/month = 10 months.
Therefore, it will take Mr. Harris 10 months to weigh 220 pounds.
