Diana received 65 points on a project for school. She can make changes and receive three-tenths of the missing points back. She can do this 10 times . Create the formula for the sum of this geometric series, and explain your steps in solving for the maximum grade Diana can receive.

    100 - 65 = 35 (assuming this is 100) she lost 35 points, she can get 3/10 of those points back '35' is the missing point * 310 = 35∗31∗10=10510=10.5 65 + 10.5 = 75.5

    I'm going to try and make sense in this, I only have a few minutes left. 100 - 65 = 35 (assuming this is 100) she lost 35 points, she can get 3/10 of those points back '35' is the missing point * \(\ \dfrac{3}{10} \) = \(\ \dfrac{35 * 3}{1 * 10} = \dfrac{105}{10} = 10.5 \) 65 + 10.5 = 75.5

    yes, the first time she missed something, and she got a 65/100, she is resubmitting to gain back 3/10ths of the missing points, 35

    So 310 = 35∗31∗10 =10510 =10.5 65 + 10.5 = 75.5 is the answer @is3535
