Write a short statement that expresses a possible function between the given variables. (price of a DVD player, demand f for DVD player)

The relation PriceVSDemand usually is an inverse relationship.

This means that, as the price of the object increases, the demand will decrease.

An inverse relationship is:

D = k/P

Where D is the demand, P is the price and K is a constant that depends on the situation.

Of course this relationship also can be something like:

D = k/P^n

With n ≥ 1.

If n = 1 we have the same as above, and if n > 1, the demand decreases faster as the price increases.

If

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70
