A pillow that usually costs $18 is marked down 25%. Use the table to find the pillow’s new price.
snow_tiger [21]

It would be 13.50 because 50% off of 18$ is 9$ but it’s not 50% off itS 25% off so If you take the 50% Off price of 9$ and add 4.50 (One more 1/4th) you get $13.50

Since opening night, attendance at Play A has increased steadily, while attendance at Play B first rose and then fell. Equations
nexus9112 [7]

Answer: option d is correct .


Step-by-step explanation:

In order to find the same attendance  we set both equation equal

8x+191 = -x^2+26x+126

simplifying equation ,we get

x^2 -18x+65=0

(x-5) (x-13) = 0

x =5  or x =13

therefore on 5th day and 13th day  both plays attendance  is same

and it is obtained by plugging x = 5 in  and x =13 in either of the equation.

for x = 5 ,

y = 8(5) +191 = 40+191 = 231

for x = 13

y = 8(13)+191

 = 104+191

 = 295

therefore option d is correct
