80% of their games are 28.8, or 29 games (since they need to win at least 80%). They have already won 16. 29-16 is 13.
Therefore, they need to win 13 more games.
P.S. The midseason statement is irrelevant.
To find the relation between them, you need transform them to the same currency. Let's transform them to cents.
$3.60 = 360 cents.
One quarter is 25 cents, and one nickel is 5 cents.
So 360 = 25q + 5n
Hope this helps! :D
If the function 1 in graph is a horizontal line y=3 then it has zero rate of change because y is same along the x axis.
Function 2 has rate of change of 2.
Y=mx+c m represents rate of change
