Answer:
$-21
Step-by-step explanation:
Since she is paying $6 for 4 weeks, in total she will pay:
6 x 4 = $24
She has an initial balance of $-45 Because she is in debt
Therefore you just need to add it all up
-45 + 24 = $-21
Answer:
y = 4x + 9
Step-by-step explanation:
okay so you already know that the tank started with 9L of water making it the y-intercept
so you need to find the slope
41-17/8-2 = 24/6 = 4
so the slope is 4
if you put all of that information together, the equation is going to look like this:
y = 4x + 9
