Answer:
7:23
Step-by-step explanation:
18400/800=23
5600/800=7

Let's evaluate ~

plug in the values :




Therefore, B is the Correct choice ~

X of 20% = y
x - y = 75
x = total amount
y = discounted amount
x * 20/100 = y
x * 0.2 = y
replace y with 0.2x in other equation
x - y = 75
1x - 0.2x = 75
0.80x = 75
x = 75/.8
x = 93.75
Check:
93.75 * 20/100 = 18.75
93.75 - 18.75 = 75
x = 93.75
y = 18.75
Answer: Total amount without discount is $93.75
//BTW not sure about this, but kind of make sense
The tuition is an illustration of a linear function.
The cost of tuition and fees in the academic year 2023-2024, is $12260
Let the number of academic years after 2014-2015 academic year be x.
So, we have:

A linear function is represented as:

Where m represents the slope (i.e. constant rate), and b represents the y-intercept (i.e. the value of y when x = 0)
So, we have:

Subtract 9200 from both sides

Divide both sides by 5

So, we have:

The function becomes


In the academic year 2023-2024, x = 9.
So, we have:




Hence, the cost of tuition and fees is $12260

The vertex form is y=a(x-h)²+k
the vertex is (h,k)
so
y=-1(x-2)²+3
compare to
y=a(x-h)²+k
2=h and 3=k
the vertex is (2,3)
