How to Calculate Cattle Population Increase with Integration

[MillerL7]

A population of cattle is increasing at a rate of 200 + 10t per year, where t is measured in years. By how much does the population increase between the 4th and 6th years. What is the total increase?

I tried doing integration and take it from the right hand site, but that was incorrect...please help me. thank you.

Can you show us what you did? Integration should have gotten you the right answer.

Sounds like you are doing this by hand. How many rectangles are you using or how many parts did you divide it into (the more parts the higher the accuracy). Also using only the right hand side will not get you an accurate answer, usually you take the right and left hand sides then average them to obtain a more accurate answer.
