linear equation that represents the total amount of quarters in the jar after days is:
Answer by math_tutor2020(3817) (Show Source): You can put this solution on YOUR website!
Answer: y = 2x + 6
Reason:
The equation is in y = mx+b form
m = 2 = slope
b = 6 = y intercept
The slope tells us how much the coin count increases. In this case, it's 2 quarters per day.
The y intercept is the starting coin count.
If x = 0, then,
y = 2x + 6
y = 2*0 + 6
y = 6
There are y = 6 quarters after x = 0 days (i.e. the starting day).
If x = 1, then,
y = 2x + 6
y = 2*1 + 6
y = 8
There are y = 8 quarters after x = 1 day
If x = 2, then,
y = 2x + 6
y = 2*2 + 6
y = 10
There are y = 10 quarters after x = 2 days
And so on.
