Answer 1

Answer:

Ben must bowl 186 in his third game in order to have an average of 170.

Step-by-step explanation:

The formula to calculate the average of given numbers is equal to the sum of all the values divided by the total number of values:

$\text{Average}=\frac{\text{Total sum of All Numbers }}{\text{Number of items}}$

Therefore,

$170=\frac{124+200+x}{3}$

Solve for x:

$\begin{gathered} 170\cdot3=124+200+x \\ 510=124+200+x \\ 510-124-200=x \\ x=186 \end{gathered}$
