Answer 1

Step-by-step explanation:

Let the number be x.

.

Form the equation:

75% of x is added to 75, the result is x

⇒ 0.75x + 75 = x

.

Solve x:

0.75x + 75 = x

Take away 0.75x from both sides:

75 = 0.25x

Switch sides:

0.25x = 75

Divide both sides by 0.25:

x = 75 ÷ 0.25

x = 300

.

Answer: The number is 300.
