Just add 41,300,000 to 50,500,000. That is 91,300,000.00 tons. Scientific Notation just moves the decimal point to the beginning. So it would be 9.13*10^7

So first you need to add the two years together to get 91,800,000 from there you can start to turn it into scientific notations. First start out by putting an imaginary decimal point at the end so you have 91,800,000. From there you need to move the decimal next to the 9 so 7 spots to the left. This means that when you are converting back from SN you would go 7 spots to the right. Therefore when you write this in SN you will have 10 to the power of positive 7.Now that you have the number and the exponent you just put them together and you have 9.18 x 10^7 . I hope this helped and if you have any questions about how I got this answer feel free to message me.
