Given:

The number of ribbons it can sell each week, x, is related to the price p per ribbon by the equation:

x=1000-100p

To find:

The selling price if the company wants the weekly revenue to be $1,600.

Solution:

We know that the revenue is the product of quantity and price.

R=xp

R=(1000-100p)p

R=1000p-100p^2

We need to find the value of p when the value of R is $1600.

1600=1000p-100p^2

1600-1000p+100p^2=0

100(16-10p+p^2)=0

Divide both sides by 100.

p^2-10p+16=0

Splitting the middle term, we get

p^2-8p-2p+16=0

p(p-8)-2(p-8)=0

(p-8)(p-2)=0

Using zero product property, we get

p-8=0 or p-2=0

p=8 or p=2

Therefore, the smaller value of p is $2 and the larger value of p is $8.

A leak in a water tank causes the water level to decrease by 3.6×10−2 millimeters each second. About how many millimeters does t
frutty [35]
The correct answer is 6.5 x 10^2.

We have the amount for 1 second. To convert to 5 hours, we need to multiply it by 60 and 60 and 5.

0.036 x 60 x 60 x 5 = 648

Or about 6.5 x 10^2
