Answer:
Sales tax
Step-by-step explanation:
You might have like 3% sales tax which is 3 percent of the original price added back onto it.
Sales tax is a tax that is put onto wanted and gourmet things, so chocolate isn't a needed item in life, so you have sales tax on it. On something like bread or meat, there might not be sales tax since you need food to survive. If something cost $100, and there is 3% sales tax, you will pay 103 dollars since 0.03 of 100 is 3.

Answer:
Step-by-step explanation:
If there needs to be 4 teachers per 21 students, you would divide the total amount of students by 21 and multiply that answer by 4. SO...:
84 ÷ 21 = 4 groups of 21 students.
4 groups × 4 teachers = 16
*** Answer***
16 TEACHERS
Vertex is -1
Axis of symmetry is -1
(Tip the axis of symmetry and vertex will always be the same)
Time is 16.75 seconds when the arrow reaches 200 ft
Step-by-step explanation:
- Step 1: Find time at height of 200 ft
Height = 200 ft
v = 280 ft/s
Projectile formula, h = -16t² + vt
⇒ 200 = -16t² + 280t
⇒ 16t² - 280t + 200 = 0
⇒ 2t² - 35t + 25 = 0 (dividing by common factor 8)
Using quadratic formula to find t
t = (35 ±√35² - 4×2×25)/2×2
t = (35 ±√1225 - 200)4 = 35 ± 32.02/4
∴ t = 67/4 or 3/4
t = 16.75 seconds
