Answer:

  • D. 0.8p(1p-0.2p)

Step-by-step explanation:

<u>If p is the original price, the markdown price is:</u>

  • p - 20% =
  • p - p(20/100) =
  • p - 0.2p =
  • 0.8p

<u>Now, another 20% off:</u>

  • 0.8p - 20% =
  • 0.8p - 0.8p(20/100) =
  • 0.8(p - 0.2p) =
  • 0.64p

<u>Answer choices:</u>

  • A. 0.2(1p-0.2p)
  • B. 0.6p
  • C. (1p-0.2p)-0.2p
  • D. 0.8p(1p-0.2p)

Correct one is D

20 POINTS WILL GIVE BRAINLIEST HELP QUICKLY!!
SVETLANKA909090 [29]

Answer:

1.function 1 has a greater rate of change than function 2

3. Function 1 has a greater y-intercept than function 2

Step-by-step explanation:

Using the table we can find the slope using

m = (y2-y1)/ (x2-x1)

m = (29-5)/ (8-0)

     = 24/8

    = 3

The rate of change for the table is 3

The y intercept is (0,5)  


Using the graph  (0,-1)  and (2,0)

m = (y2-y1)/ (x2-x1)

m = (0--1)/ (2-0)

     = (0+1)/2

    = 1/2

The y intercept is (0,-1)


Since 3>1/2 , function 1 has a greater rate of change than function 2

Since 5>-1, function 1 has a greater y-intercept than function 2
