Daniel works at an electronics store, and he claims that the popularity of a television (measured in number of sales) is inverse
Rom4ik [11]

We are given that popularity of television is inversely proportional to its cost.

let us say popularity of television is represented by "P" and cost of television by "T".

We will use a constant "k" to convert the proportionality sign to equal to (=) sign.

Thus forming the equation :

P= \frac{k}{T}

We are given that 15 customers buy a television that cost $1500.

plugging P=15 and T=1500, finding k,

15= \frac{k}{1500}

k=15*1500 = 22500

Next we have to find how many customers would buy a television that costs $2500, so here k=22500 and T=2500, plugging this in the equation we have ,

P= \frac{22500}{2500}

P=9

So there will be 9 customers that buy a television which costs $2500.
