Answer:
The exact interest on $5,870 at 12% is $410.9
Step-by-step explanation:
From the information provided we know that
Principal amount: $5,870
Interest rate: 12% -> 0.12
Time: 7 months (From June to December)
When you know the principal amount, the rate, and the time, the amount of interest can be calculated by using the formula:

where P is principal, r is the rate of interest and t is the time in years.
We need to convert the 7 months into 1 year.

Now we can use the above formula

Therefore the exact interest on $5,870 at 12% is $410.9

Using variable concepts, of dependent and independent variables, it is found that the dependent variable is the amount of sales dollars earned.
<h3>What is the relation between a function and the dependent and independent variables?</h3>
- A function has the following format: y = f(x).
- In which each value of y is a function of one value of x, and thus, <u>x is the independent variable and y is the dependent variable</u>.
- That is, the input of the function is the independent variable and the output is the dependent variable.
In this problem, the manager believes that the amount of sales dollars earned is a function of the number of contacts that the salesperson makes, hence:
- The number of contacts is the independent variable.
- The amount of sales dollars earned is the dependent variable.
