50% OFF! The sale price of a refrigerator is $300. What was the original price?

$600

Step-by-step explanation:

Because 50% is just half of the original price. It would be adding 300 back to itself.

For example. Let's answer the same problem just with a different number. $200 for example.

200 is 50% of what? What is 200 half of? 400.

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)
