Divide 3 by 3/4 and you will get your answer. you can also multiply 3×4/3. it's the same thing
Answer:
a) answered in the image attached
b) y=2.75x+3.50
c) y=2.75(5)+3.50
y=17.25
Answer:

Using this condition we got:

And solving for b we got:

So then our linear function is given by:

Where y is the amount of fluid left and x the number of hours ellapsing
Step-by-step explanation:
We want to set up a linear function like this one:

Where y is the amount of fluid left, m the slope and b the initial amount. From the info given we know thatm = -300. And we also have the following condition:

Using this condition we got:

And solving for b we got:

So then our linear function is given by:

Where y is the amount of fluid left and x the number of hours ellapsing
