The number of ants in his farm after 12 weeks is 218.
Step-by-step explanation:
Step 1:
It is given that there are 15 ants initially and the ant population increases by 25% each week.
This is an exponential rate of increase that can be modeled by the following equation:
Number of ants after n weeks = Initial number of ants * 
Step 2:
Rate of increase = 25% = 25 / 100 = 0.25
Number of weeks = 12
Number of ants after 12 weeks = 15* 
= 218.27 (rounded off to 218)
Step 3:
Answer:
The number of ants in his farm after 12 weeks is 218.

<h3>T
he monthly payment is $242.44 for loan to paid off in 3 years.</h3>
Step-by-step explanation:
The amount borrowed = Principal = $8000
The rate of interest = 7.2%
Time (T) = 3 years
Now, Simple Interest = 
So, the total interest = $1728
Now, <u>Amount to be paid = Principal + Interest</u>
⇒ A = $8000 + $1728 = $8728
Also, 1 year = 12 months
⇒ 3 years = 3 x 12 months = 36 months
So, total amount to be paid in 36 months is $8728.
⇒The amount to be paid in 1 month is 
Hence, the monthly payment is $242.44 if loan is to paid off in 3 years.
