A company has determined that the number of items it sells varies inversely as the price of the item. If 20,000 items can be sol

mestny [16]

Let N be the number of items sold and p the price.
Since the variation is inverse, then the relation between N and p is:
$N=k\dfrac{1}{p}$
For N=20000 and p = $9.5, we get the formula:
$20000=k\dfrac{1}{9.5}\\p=20000\times9.5=190000$
If p = 8.75, then the number of items sold can be computed using the formula:
$N= 190000\dfrac{1}{8.75}=21714 \text{ total items}$

klio [65]

Answer:

Then as the plumber charges $30.75 per hour we have that $\frac{\$ 184.50}{\$ 30.75/h}=6h$ is the maximum amount of hours that Sarah can have the plumber work on her faucet.
