Mele earned scores of 75, 70, 92, 95, and 97 points (a total of 429 points) on the first 5 tests in Economics II. Solving which of the following equations for s gives the score he needs to earn on the 6th test to average exactly 85 points for all 6 tests?

• 
  

  $\frac{429}{5}+s=85$

• $\frac{429}{6}+s=85$

• $\frac{\left(s+429\right)}{5}=85$

• $\frac{\left(s+429\right)}{6}=85$

• $\frac{\left(s+429\right)}{6}=\frac{85}{100}$
