Answer:
By scoring 240 in the sixth game, Marlon can maintain this exact average
Step-by-step explanation:
The first thing to do here is to calculate the average for the first 5 games.
Mathematically, the average can be calculated by adding all the scores in the games and dividing by 5;
= (210 + 225 + 254 + 231 + 280)/5 = 1200/5 = 240
Now to maintain this average score of 240, we want to know the score she must have in the 6th game.
Let the score be x;
By adding x to the previous total of 1200 before and dividing by the new count of 6, we can work our way to get x.
Mathematically, what we are saying is;
(1200 + x)/6 = 240
6 * 240 = 1200 + x
1440 = 1200 + x
x = 1440 -1200
x = 240
