To find the mean, add all the values and then divide the sum by how many values you added. In this case, if the teacher drops the lowest score (68) that would leave 5 values. So,
90 + 83 + 88 + 74 + 80 = 415 < this is the total of all (minus the lowest) or Lorenzo's test scores. Now take this number, and divide it by 5 (because we added five tests together):
415 / 5 = 83 < this is the new mean, and also his percentage grade.
Answer: 83
Alternatively, you can list the grades from least to greatest, and cancel one value from each side until you get to the middle.
There will be 18 sheep and 15 ducks.

18 sheep x 4 legs per sheep =72 legs
15 ducks x 2 legs per duck = 30 legs
72+30= 102 legs in all
