There are 25,000 trees in a forest . If the target rate for growth in the number of trees is 10% per year, what will their number be after 3 years? Options: 32700 trees 25600 trees 33275 trees About the author Parker
Answer: 33275 Step-by-step explanation: After 1 years: No. of trees = 25000 + 10% of 25000 = 25000 + 2500 = 27500 After 2 years: No. of trees = 27500 + 10% of 27500 = 27500 + 2750 = 30250 After 3 years: No. of trees = 30250 + 10% of 30250 = 30250 + 3025 = 33275 Or directly, use: No. of trees = 25000 x (1 + r)ⁿ = 25000 x (1 + 10/100)³ = 33275 Reply
Answer:
33275
Step-by-step explanation:
After 1 years:
No. of trees = 25000 + 10% of 25000
= 25000 + 2500
= 27500
After 2 years:
No. of trees = 27500 + 10% of 27500
= 27500 + 2750
= 30250
After 3 years:
No. of trees = 30250 + 10% of 30250
= 30250 + 3025
= 33275
Or directly, use:
No. of trees = 25000 x (1 + r)ⁿ
= 25000 x (1 + 10/100)³
= 33275
