Answer:
The second equation is correct.
y=2.25x + 4
Step-by-step explanation:
We can systematically eliminate the others.
For equation 3 and 4, 6.5*2 and 12*x is already bigger than 8 of the first set of numbers.
For equation 1, 2*x+8.5 is also bigger than 8 from the first set.
Plugging in the values to equation 2, we always get the correct cost.

We are given that the distribution of amount of money spent by students is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.975
Calculation the value from standard normal z table, we have,
Approximately 97.5% of the students spent below $275 on textbook.
