Answer:</h3>
y = -5x -1
<h3>
Step-by-step explanation:</h3>
Changes in x-values are constant and are +1.
Changes in y-values are constant and are -5.
Because the ratio of changes in y to changes in x is constant (-5/1) = -5, you know the function is linear. To write the equation, you can use the slope-intercept form, since you know the slope (-5) and the table shows the y-intercept: (x, y) = (0, -1).
The rule is ...
... y = -5x -1
63%
First, we have to take 20.00 - 7.40 which gets us 12.60.
Then, we use the formula where we put the 12.60 on top of a fraction bar, and the 20.00 on bottom.
We do 12.60 x 100 which makes 1260.
Lastly, we divide that by the 20.00 which gets us 63.
So, Julie has 63% of her money left.
I hope this helped!!!
