If the 60% is worth 25% of her mark that is worth 1/4 of her mark. The 75% previous average is worth 3/4 of her mark. That means we can add 60 + 75 + 75 + 75. If we total those marks we get 285. Then we divide by the number of marks (4). So 285/4=71.25%

To calculate Susan's final grade, we need to consider the weight of her previous average and her final paper. The previous average is worth 75% and the final paper is worth 25%.

First, let's calculate the contribution of the previous average to Susan's final grade. The previous average is 75% of her final grade, so it will be worth 0.75 * 75% = 56.25%.

Next, let's calculate the contribution of the final paper to Susan's final grade. The final paper received a mark of 60%, and it is worth 25% of her final grade, so it will be worth 0.6 * 25% = 15%.

Now, we can calculate Susan's final grade by adding the contribution from her previous average and the final paper: 56.25% + 15% = 71.25%.

Therefore, Susan's final grade after receiving 60% on her final paper will be 71.25%.
