To solve this, we have to work backwards. If you divide something by 9, and it equals 5, to figure out the number, we need to multiply by 9. 5*9= 45. If four was taken away, we have to add it to 45, which is 49. If a number *7 is 49, then we have to divide by 7 to get the answer. 49/7=7

Jake's final grade in his science class is calculated by finding the mean of his scores for six project reports. The score Jake

The lowest possible score that Jake can have is 92.

To solve a problem like this, you need to find the average of the data set. To do that, you add up all the given numbers and divide the total by how many numbers were added up.

To find this answer, I just added in each letter one at a time (for C, I did 66+80+88+82+72+92, which equals 480, and then I divided it by 6 to get 80.) until I got an answer of 80.
