Question

A producer of personal computer mouse pads determines that the number, N, of pads sold is related to the price, X, of a pad by N=35x-x^2. at what roice is th ecost so high, that no one wants to buy the any mouse pads?

Answer 1

Answer:

If the cost X is higher or equal than 35, then no one wants to buy the any mouse pads.

Step-by-step explanation:

When N is 0 or lower then it means that no one buys it.

N=35x-$x^{2}$, if N=0 then

0=35x-$x^{2}$ or

35x=$x^{2}$ dividing each side by x we get:

35=x

This is the cost which nobody will buy the mouse pad anymore.
