Question

Wayne Gretzky holds the NHL record for the most points scored In a career. He scored 2857 points in 1487 games. a. Calculate his average points per game b. At this rate,how many more points might he have scored if he had played 79 more games?

Answer 1

a. 1.92

b. 152

Explanation:

Wayne Gretzky had 2857 points in 1487 games.

a. His average points per game can be determined by dividing the total number of points by number of games. So that:

average points per game =
`(2857)/(1487)`

= 1.92132

Therefore, he scored an average of 1.92 (2 d.p) points per game.

b. The number of points he would have scored having played 79 more games can be determined by multiplying the points for 79 more games by his average points.

His points for 79 more games = 79 × 1.92132

= 151.78428

He would have scored 152 (3 s.f) more points if he had played 79 more games.

Answer 2

Explanation:

a) The formula for determining average is expressed as

Average point per game = number of points scored/total number of games played

Average point per game = 2857/1487 = 1.92

b) if he had played 79 more games, since his average point per game is 1.92, then the number of points that he might have scored would be

1.92 × 79 = 95 points

The total number of points would have been

2857 + 95 = 2952 points
