Answer 2

Answer:

85.

Step-by-step explanation:

We have been given that the final score in a math contest is made up of 50% test scores, 25% oral participation scores, and 25% project scores.

To find Ella's final scores we need to figure out 50% of 85, 25% of 95 and 25% of 75 and add them all.

$\text{Ella's final scores}=(\frac{50}{100}\times 85)+(\frac{25}{100}\times 95)+(\frac{25}{100}\times 75)$

$\text{Ella's final scores}=(0.50\times 85)+(0.25\times 95)+(0.25\times 75)$

$\text{Ella's final scores}=42.50+23.75+18.75$

$\text{Ella's final scores}=85$

Therefore, Ella's final score in the contest would be 85.
