To find the average temperature last Sunday, we need to add 8% of the average temperature two Sundays ago to the average temperature two Sundays ago.
Choice A is incorrect because it represents the average temperature as 108% of the original temperature, which is too high.
Choice B is correct because it represents the average temperature as the original temperature plus 8% of the original temperature.
Choice C is incorrect because it represents the average temperature as the original temperature plus 0.08, which is not the correct way to calculate a percentage increase.
Choice D is incorrect because it represents the average temperature as 180% of the original temperature, which is too high.
Choice E is incorrect because it represents the average temperature as the original temperature plus 8, which is not the correct way to calculate a percentage increase.
Therefore, the correct choices are \[\left(1+\frac{8}{100}\right)T\] and \[T+0.08\] which are choices B and C.

Apologies for the mistake. Let's re-evaluate the choices.
Choice A is still incorrect because it represents the average temperature as 108% of the original temperature, which is too high.
Choice B is correct because it represents the average temperature as the original temperature plus 8% of the original temperature.
Choice C is still incorrect because it represents the average temperature as the original temperature plus 0.08, which is not the correct way to calculate a percentage increase.
Choice D is incorrect because it represents the average temperature as 180% of the original temperature, which is too high.
Choice E is incorrect because it represents the average temperature as the original temperature plus 8, which is not the correct way to calculate a percentage increase.
Therefore, the correct choices are \[\left(1+\frac{8}{100}\right)T\] which is choice B.
