Answer: 300 feet

<h3 /><h3>Step 1: Get to 1</h3>

The biggest challenge in this problem is that it includes a fraction.

So, we can make this question easier by figuring out how many feet this train travels in 1 second.

If we know how far it traveled in 1 second, then we can quickly figure out how far it goes in 4 seconds.

Since the train travels 25 feet in 1/3 of a second, then it must travel 3 times that far in 1 second:  

25 feet x 3 = 75

We now know that this train must travel 75 feet in 1 second. Now we can solve for 4 seconds quite simply.

<h3>Step 2: Extrapolate</h3>

If the train travels 75 feet in 1 second, then how far will it travel in 4 seconds? We need to multiply 75 by 4 to get our answer:

75 x 4 = 300 feet

serg [7]

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.
