at $16 per DVD. If Rebecca orders 6 DVDs,
how much does it cost?

Dependent:

Independent:

Continuous or Discrete:

Function:

Solution:

Answer 1

Dependent = cost

independent = number of DVDs

Discrete

Function :f(x) = 16 x = 16 (6)

Solution = $96

Explanation:

Hi, to answer this question we have to write a function:

The cost (f(x)) must be equal to the price per DVD (16) multiplied by the number of DVDs (x)

Function: f(x) = 16 x

Dependent = f (x) =(cost)

Independent = x (number of DVDs)

Solution for x=6

f(6) = 16 (6)

Cost = $96

Since the number of DVDs can't be fractional it's a Discrete function.
