Has to be 9......because the area is l x w and 9x9 = 81
The least number of points Jared needs to score is 53.
Jared already has an average of 86%. He want to have an overall average of 88. His exam is worth 20% of the total grade. This information can be modelled as:
(0.8 x 86%) + (0.2 x a) = 88%
a = score in the exam.
68.8 + 0.2a = 88%
Combine similar terms
0.2a = 88 - 68.8
0.2a = 19.2
a = 19.2 / 0.2
a = 96%
Jared has to score 96% on the exam.
The second step is to determine which score would give 96%
x / 55 = 96%
x = 55 x 0.96
x = 52.8
x = 53
