Question

Suppose that for you to make the golf team you need to score no more than 74 on average over 5 games. If you scored 77,71,77, and 67 in your first 4 games. What is the highest score you can shoot in your 5th game and still make the team?

Answer 1

(77 + 71 + 77 + 67 + x) / 5 < 74
(292 + x) / 5 < 74
292 + x < 74 * 5
292 + x < 370
x < 370 - 292
x < 78...the highest score u can shoot is 77 

Answer 2

Answer:

The highest score we can shoot in our 5th game and still make the team is:

         78

Step-by-step explanation:

We scored 77,71,77, and 67 in our first 4 games.

Let score in fifth game be x

If we want a average score of no more than 74 over 5 games,then

    $\dfrac{71+77+77+67+x}{5}\leq 74$

       $\dfrac{292+x}{5}\leq 74$

                292+x≤370

                      x≤370-292

                     x≤78

Hence, the highest score we can shoot in our 5th game and still make the team is:

         78
