We are given that Kristine spends $20 and saves the rest each time she get paid.
We can use slope-intercept form y=mx+b to represent the equation.
Where x represents the amount Kristine earns and y represents the amount she saves.
Kristine spends $20. Therefore b= -20.
Plugging mx as just x and b=-20.
<h3>y = x-20.</h3><h3>If we plug y=0, we get </h3><h3>0 = x-20</h3><h3>x=20.</h3><h3>We can see in 4th option we have x-intercept =20.</h3><h3>Therefore, correct option is 4th option. </h3><h3 />

Answer:
285 centiliters
Step-by-step explanation:
Using the given conversion factor:
1 quart = 0.95 L = 95 cL
3 quarts = 3 × 95 cL = 285 cL
There are approximately 285 centiliters in 3 quarts.
__
Centi- is a prefix meaning 1/100th. So, 0.95 L (95 hundredths) is 95 cL.
