You plant a tree that is 36 inches tall. After one year, the tree is 43 inches tall. Which expression describes the percent of increase in the tree's height?
Answers
Answer: is the required expression.
Step-by-step explanation:
Since we have given that
Length of tree initially = 36 inches
Length of tree after one year = 43 inches
We need to find the percentage of increase in the tree's height.
So, expression would be
Hence, is the required expression.
(43 - 36) ÷ 36 = 7 ÷ 36 = 0.1944 * 100% = 19.44%
36 is the basis of the equation. It is the 100%
7 is the increase in height (inches). It is the 19.44%
43 is the total height. It is 119.44% height of the tree.
Whatever height the tree grow to, if the question is percentage since it was planted, then 36 inches is the basis.
If the problem refers to the height increase based on the latest height measurement, then 43 inches is the basis.
If the 7 inches increase in height is constant every year. Then, an equation will show:
y = 36 + 7x
where y is the total growth through the years. 36 is the initial height, 7 is the constant rate of growth, and x is the number of years the tree has grown.

Part A: Calculate the corresponding unit rate for each package.
Part B: Interpret what the unit rates found in Part A represent.
Part C: Choose which package is the best buy.
Answers
Data given:
➀ Pop-A-Lot: 7 ounces for $3.50
➁ Pop Kornz: 8 ounces for $4.25
➂ Pop-arazzi: 17 ounces for $7.49
➃ Kernels Popcorn: 3 ounces for $2.05
Explaination:
We divide the cost by the number the ounces to find the unit price. a.k.a the price per ounce.
Work:
➀ 3.50 ÷ 7 = 0.5
50 cents
➁ 4.25 ÷ 8 = 0.53125
53 cents (rounded)
➂ 7.49 ÷ 17 = 0.440588235
44 cents (rounded)
➃ 2.05 ÷ 3 = 0.683333333
68 cents (rounded)
Answer:
Part A:
➀ Pop-A-Lot: 50 cents per ounce of popcorn
➁ Pop Kornz: 53 cents per ounce of popcorn
➂ Pop-arazzi: 44 cents per ounce of popcorn
➃ Kernels Popcorn: 68 cents per ounce of popcorn
Part B: The unit rates found in Part A represent the cost per each ounce of popcorn
Part C: The best package to buy is Pop-arazzi because it cost less per-pound of popcorn. (44 cents per ounce of popcorn)
44¢ < 50¢ < 53¢ < 68¢
➂ < ➀ < ➁ < ➃
Pop-arazzi < Pop-A-Lot < Pop Kornz < Kernels Popcorn
Answer:
PART A
Unit Rate for Pop-A-Lot Pop Kornz = $7.44 / 6 ounces
Unit Rate for Pop-arazzi Kernels Popcorn = $4.32 / 8 ounces
Unit Rate for Pop Kornz = $6.27 / 11 ounces
Calculating these unit rates:
Unit Rate for Pop-A-Lot Pop Kornz ≈ $1.24 per ounce
Unit Rate for Pop-arazzi Kernels Popcorn ≈ $0.54 per ounce
Unit Rate for Pop Kornz ≈ $0.57 per ounce
PART B
Brepresent the cost per ounce of each package. It shows how much you would need to pay for each ounce of popcorn in each specific package.
PART C
To determine the best buy, we compare the unit rates.
Pop-A-Lot Pop Kornz: $1.24 per ounce
Pop-arazzi Kernels Popcorn: $0.54 per ounce
Pop Kornz: $0.57 per ounce
Based on the unit rates, the best buy would be Pop-arazzi Kernels Popcorn, as it has the lowest unit rate of $0.54 per ounce.

Explanation:
Let's first assume few variables!
x = Ishann's age (in years)
y = Christopher's age (in years)
1. Ishann is 3 times as old as Christopher can be represented mathematically as:
x = 3y ---- (1)
2. Ishann is 14 years older than Christopher can be represented mathematically as:
x = y + 14 ---- (2)
Get the value of y from Equation (1) and plug it in Equation (2):
(2) => x = (x/3) + 14
3x = x + 42
2x = 42
x = 21
Hence Ishann is 21 years old!
