the profit, p dollars, earned by a saleswoman selling scented candles is approximated to be p=-10x^2+300x-250, where x dollars is the selling price of one scented candle. what selling price gives the maximum profit?
$10
$30
$15
$7.50

the selling price that gives the maximum profit is $15

Step-by-step explanation:

The profit, P dollars, earned by a saleswoman selling scented candles is approximated to be P=-10x^2+300x-250

This is a quadratic equation and the graph of P against x will give a parabola with a vertex whose value will be the maximum price

The maximum price occurs at x =

-b/2a

From the equation,

a = -10

b = 300

c = - 250

-b/2a = -300/2×-10= -300/-20

= 15

This gives the vertex of the parabola

Therefore, the selling price that gives the maximum profit is $15

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
