Mark me as the brainliest

Step-by-step explanation:

In a forest there are 40,000 trees. Find the expected number of trees after 3 years if the objective is to increase the number at the rate 5% per year. A = 40000 (1+0.05)3 A = 40000 (1.05)3 A = 40000 (1.157625) ∴A= 46305/- ∴ The expected number of trees after 3 years will be 46305.

$\textsf{Answer: 46,000 trees ☑}$

$\blue{\sf{\star\;Appropriate\; Question}}$

• In a forest there are 40,000 trees.Find the expected number of trees after 3 years if the objective is to increase the number of trees by 5% every year

$\pink{\sf{\star\;Required\; Solution}}$

$\textsf{1:Method}$:-

• $\textsf{At starting number of trees are 40,000.}$

• $\textsf{Objective is to increase 5%}$

• $\textsf{so 5% of 40,000 = (5*40000)/100}$

• $\textsf{= 20,0000/100}$

• $\textsf{= 2000}$

• $\textsf{In one years 2000 plants to be planted,so in three years = 3*2000 trees}$

• $\textsf{= 6000 trees}$

• $\textsf{Expected number of tree after 3 years = 46,000 trees. ✔}$

$\green{\sf{\star\;Explanation\; Needed!}}$

$\textsf{2: Method}$:-

2) If 5% is calculated on present trees

after 1 year total trees 42,000.

• $\textsf{5% of 42,000= (5*42000)/100}$

• $\textsf{=2100}$

• $\textsf{after second year trees are 42000+2100}$

• $\textsf{= 44100 trees}$

• $\textsf{5% of 44100 = (5*44100)/100}$
• $\textsf{= 2205}$

• $\textsf{after 3 year expected trees= 44100+2205}$

• $\textsf{= 46305 trees. ✔}$
