Answer:

1. The population increases exponentially, therefore the number of members in the team will increase by the equation modeled by :

\text{Number of members = }a_0(1+\frac{Rate}{100})^{Time}\\\\\implies\text{Number of members = }412(1+\frac{5}{100})^9\\\\\implioes\text{Number of members after 9 months = }639

2. Total cost of the toy is calculated by multiplying the initial cost and the amount of tax charged on the toy.

Here, 15.85 represents the initial cost of the toy

Hence, 1 + x represents the amount of tax charged on the toy.

3. Rate per year is given to be 12.5%

Now, to find monthly rate, divide the yearly rate by 12

\text{Monthly Rate = }\frac{12.5}{12}=1.04\%

4. Rate per year is given to be 20%

Now, to find monthly rate, divide the yearly rate by 12

\text{Monthly Rate = }\frac{20}{12}\approx 1.7\%

5. The value of a truck after t years is represented by the function f(t)=22,200(0.92)t .

Here, 2200 is the initial value of the truck.
