Final answer:

To find the rate of change in weight, subtract the initial weight from the final weight and divide by the time period. In this case, the rate of change is approximately 2.14 lbs/year.

Explanation:

To find the rate of change in this scenario, we can use the formula: rate of change = (final value - initial value) / time. In this case, the final value is 190lbs, the initial value is 145lbs, and the time is 2007 - 1986 = 21 years.

Substituting these values into the formula, we get: rate of change = (190 - 145) / 21 = 45 / 21 = 2.14 lbs/year.

Therefore, the rate of change in weight for this student is approximately 2.14 lbs/year.
