I would tell her not to because not only does she have to pay back the 1000 but now she also has to pay back the interest on it. She should just wait or save up until she has 1000 that way she dont gotta pay extra.
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
Answer: d) $369.31 to $380.69
Step-by-step explanation:
Given;
Mean price x= $375
Standard deviation r= $20
Number of retail stores n = 50
Confidence interval of 95%
Z*(95%) = 1.96
Confidence interval = x+/-Z*(r/√n)
= $375+/- 1.96(20/√50)
= $375+/- 5.69
Confidence interval = ($369.31 to $380.79)
