Not sure if there is a correct answer here, but here are some reasons:
1. They haven't slept well the night before, due to homework, projects, and even using devices (like our phone) for too long. Waking up early for school will result in sleeping students in class. Even the environment of the class can put them to sleep (ex. dim lights, quiet students, etc.)
2. They are bored. Someone who hates math or history will start to yawn as soon as the teacher begins explaining (ex. even if they were just so energetic in gym class the period before).
On the graph, we will adjust the supply and demand curves to illustrate the decrease in the price of calzones by making the supply curve shifts to the right.
<h3>What happen when
supply curve shifts to the right?</h3>
When the supply curve shifts to the right, its means that there is an increase in the change in supply.
Hence, the increase in the change in supply makes price of product reduces at there is enough availability of the product.
In conclusion, we will adjust the supply and demand curves to illustrate the decrease in the price of calzones by making the supply curve shifts to the right.

Answer:
TFC : Horizontal Line parallel to X axis
TVC : Upward sloping inverse S shape curve from origin
TC : Upward sloping increase S shape curve, with Y axis intercept = TFC
Explanation:
Total Fixed cost [TFC] is the total production expenditure, done on fixed factors of production (Eg - on machine, building etc). It is incurred even at zero level of output, stays same (constant) irrespective of output level. So, it's curve is a constant horizontal line.
Total Variable Cost [TVC] is the total production expenditure, done on variable factors of production (Eg - on raw material). It is zero at zero level of output, directly related to level of output thereafter. It first increases at a decreasing rate, then increases at an increasing rate. So, it's curve is inverse S upward sloping curve from origin.
Total Cost [TC] is the total cost incurred on all factors of production (fixed & variable). It is sum of TVC & TFC. As TFC is constant at all levels of output, TC changes due to change in TVC. So, TC is also directly related to output level, first increases at increasing rate & then at decreasing rate. Hence, it is also a inverse S upward sloping curve. But, it also includes constant TFC. So, the curve has intercept on Y axis = TFC (it doesn't start from origin).

The equation for the value of an investment with periodic contributions is:
B = P(1+r)^y + c(((1+r)^y -1)/r)
where
B = Balance
P = Initial principle
r = interest rate
c = periodic contribution
y = number of years.
For this problem, the initial principle is 0, so we have a simplified equation of:
B = c(((1+r)^y -1)/r)
Let's solve for c, substitute the known values, and calculate
B = c(((1+r)^y -1)/r)
B/(((1+r)^y -1)/r) = c
1000000/(((1+0.10)^20 -1)/0.10) = c
1000000/(((1.10)^20 -1)/0.10) = c
1000000/((6.727499949 -1)/0.10) = c
1000000/(5.727499949/0.10) = c
1000000/57.27499949 = c
17459.62477 = c
So Zheng needs to contribute $17,459.62 at the end of every year.
