A rice store estimates that if it sells each pack of rice forxdollars, then the projected number of packssold daily is 240−10x. What is the price per pack that maximizes its daily profit?

Price per pack = 12

Step-by-step explanation:

The profit can be calculated as the product of the price by the quantity sold:

P = x * (240-10x)

P = -10x^2 + 240x

To find the maximum of this quadratic function, we can use the formula to find the vertix:

x_v = -b/2a

Where a and b are coefficients of the quadratic equation (a = -10 and b = 240)

x_v = -240/(-20) = 12

Now, we use this value to find the maximum profit:

P_max = -10*(12)^2 + 240*12 = 1440

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
