The average rate of change in the calf's weight can be calculated by taking the total change in weight and dividing it by the total number of days. From day 1 to day 40, the weight changed from 505 lbs to 700 lbs, a change of 195 lbs over 39 days. $ \frac{195 \text{ lbs}}{39 \text{ days}} = 5 \text{ lbs per day} $.
