Pippin went to a game room that charged $4 admission, plus $0.25 per token. The equation which represents his total cost is y = 0.25x + 4.What are the ordered pairs for the equation when you use these x-values: 5, 10, 20?(5, 5), (10, 8), (20, 15)(5, 8), (10, 10), (20, 15)(5, 5.25), (10, 6.50), (20, 9)(5, 5.50), (10, 8.50), (20, 13)

Answer:

(5, 5.25) , (10, 6.50) , (20, 9)

Step-by-step explanation:

As given ,

y = 0.25x + 4

Now,

if x = 5

⇒ y = 0.25(5) + 4

      = 1.25 + 4

     = 5.25

⇒ y = 5.25

∴ the ordered pair be (x, y) = (5, 5.25)

if x = 10

⇒ y = 0.25(10) + 4

      = 2.5 + 4

     = 6.50

⇒ y = 6.50

∴ the ordered pair be (x, y) = (10, 6.50)

if x = 20

⇒ y = 0.25(20) + 4

      = 5 + 4

     = 9

⇒ y = 9

∴ the ordered pair be (x, y) = (20, 9)
