Final answer:

To meet his weight gain goal, Scott would need to eat approximately 2953 calories per day.

Explanation:

To calculate the total calories per day that Scott would need to eat to meet his weight gain goal, we need to multiply his current weight gain rate (1 pound per week) by the number of calories needed to gain 1 pound, which is 3500 calories. Then, we divide the result by 7 days to determine the number of extra calories Scott needs to consume per day. Finally, we add this value to his recommended energy intake for weight maintenance, which is 40 calories per kilogram body weight.

First, let's convert Scott's weight from pounds to kilograms. 135 lb * 0.454 kg/lb = 61.47 kg (rounded to 61.5 kg).

Next, we calculate Scott's weight gain rate per day: 1 lb * 3500 calories/lb / 7 days = 500 calories per day.

Finally, we add Scott's weight gain rate to his recommended energy intake for weight maintenance: 61.5 kg * 40 calories/kg + 500 calories/day = 2453 calories + 500 calories = 2953 calories per day.
