4) Tony pays $245 for a PS4. He decides to sell the PS4 with a 30% markup. How much is Tony selling the PS4 for?

318.5

Step-by-step explanation:

30% of 245 is 73.5

245 + 73.5 = 318.5

1,645,493,059.35

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
