In our school netball league a team gains a certain whole number of points if it wins a game, a lower whole number of points if it draws a game and no points if it loses a game. After 10 games my team has won 7 games, drawn 3 and gained 44 points. My sister's team has won 5 games, drawn 2 and lost 3. How many points has her team gained?

Since 5 points are awarded for a win and 3 points for a draw, your sister's team has earned 31 points.

The way I did it was by dividing 44 points by 10 games, which gave me 4.4.  Then I just tried the whole numbers around 4.4.  The first ones I tried were 5 & 3 and they worked.  I tried 6 & 2 and they don't work.

You cant do 44/10 this is because 44 is not the max amount of points you can get!

Regarding your "You cant do 44/10 this is because 44 is not the max amount of points you can get!"

Sure I can.  It worked didn't it!  I didn't "do" 44/10 for the reason that it was the maximum amount of points possible, but because it was the amount of points the team DID get.

The answer is 31. This is because if he has 7w and 3d it means that 7w+3d=44. From this we know that one W is bigger then 1 but smaller then seven. A win cannot be 6 points because then a draw would be 0.666 repeated! That means that it is 5,4,3,or 2. If we plug in 5 then we will get that one draw is 3 points! After we find this we can do 5*5+3*2+0 because she has 5 wins, 2 draws, and 3 losses and because a win is 5 points, a draw is 3 points, and a loss is 0 points the answer is 31! Hope you liked my explanation!
